# Automated Testing
-OboeTester can be used to measure the round trip latency and glitches.
+OboeTester can be used to measure the round trip latency and glitches.
It can be launched from a shell script by using an Android Intent.
Before running the app from an Intent, it should be launched manually and a Round Trip Latency test run. Then you can give permission for using the microphone to record the looped back sound, and give permission to write to external storage for saving the test result.
## Requirements
+All tests require:
+
* host computer
+* ADB installed
* ADB USB cable
+
+The latency, glitch and data_paths tests also need:
+
* [loopback adapter](https://source.android.com/devices/audio/latency/loopback)
* a 3.5 mm jack on the phone*
-\* If you don't have a 3.5 mm jack then you can use a USB-C to 3.5mm adapter. Then you will also need a USB switching device such as [TigerTail](https://go/tigertail).
+\* If you don't have a 3.5 mm jack then you can use a USB-C to 3.5mm adapter.
+In order to use ADB at the same time you will also need a USB switching device
+or use ADB/Wifi.
+Internally at Google, the [TigerTail](https://go/tigertail) device can be used for USB.
## Start App from Intent
The app can be started by sending a Start comment to the OboeTester class.
The app will run and the results will be written to a file.

+## Recorded Audio
+
+[OboeTester](README.md) can record audio.
+The data is only used to test the audio recording capability of your device.
+These tests include:
+
+* measuring round-trip audio latency
+* measuring glitches by listening to an output sine wave
+* recording audio for immediate playback and listening
+
+Audio recording is always initiated by a button press.
+
+It is possible for you, the user, to share WAV files that have been recorded.
+You can email them to someone, or upload them to Google Drive, or send them to other Sharing destinations.
+This is optional. No recorded audio is uploaded or saved by the program unless the user requests it.
+
+## Phone State
+
+OboeTester can also check and modify the phone state. This is only used for testing modes like "Speaker Phone" or turning on or off Bluetooth SCO.
+
+## Test Results
+
+The user can ask OboeTester to run automated tests that look for audio bugs or measure performance.
+These generate reports that contain the results of the test plus information about the phone including:
+
+* manufacturer (eg. Samsung)
+* model (eg. S10)
+* version and build information (eg. Pie 9.0)
+* audio performance metrics (eg. latency, glitch rate)
+* audio feature support (eg. AAudio MMAP)
+
+But you, the user, can can email them to someone, or upload them to Google Drive, or send them to other Sharing destinations.
+This is optional. No reports are uploaded or saved by the program unless the user requests it.
+
+The source code for Oboetester is available [here](https://github.com/google/oboe/tree/main/apps/OboeTester) on GitHub.

# Frequently Asked Questions (FAQ)
-## Can I write audio data from Java to Oboe?
+## Can I write audio data from Java/Kotlin to Oboe?
Oboe is a native library written in C++ which uses the Android NDK. To move data from Java to C++ you can use [JNI](https://developer.android.com/training/articles/perf-jni).
-That said, if you are generating your audio in Java you'll get better performance using the [Java AudioTrack class](https://developer.android.com/reference/android/media/AudioTrack). This can be
-created with low latency using the AudioTrack.Builder method [`setPerformanceMode(AudioTrack.PERFORMANCE_MODE_LOW_LATENCY)`](https://developer.android.com/reference/android/media/AudioTrack#PERFORMANCE_MODE_LOW_LATENCY).
+If you're generating audio data in Java or Kotlin you should consider whether the reduced latency which Oboe gives you (particularly on high-end devices) is worth the extra complexity of passing data via JNI. An alternative is to use [Java AudioTrack](https://developer.android.com/reference/android/media/AudioTrack). This can be created with low latency using the AudioTrack.Builder method [`setPerformanceMode(AudioTrack.PERFORMANCE_MODE_LOW_LATENCY)`](https://developer.android.com/reference/android/media/AudioTrack#PERFORMANCE_MODE_LOW_LATENCY).
You can dynamically tune the latency of the stream just like in Oboe using [`setBufferSizeInFrames(int)`](https://developer.android.com/reference/android/media/AudioTrack.html#setBufferSizeInFrames(int))
Also you can use blocking writes with the Java AudioTrack and still get a low latency stream.
@@ -14,12 +13,12 @@
Note that [`AudioTrack.PERFORMANCE_MODE_LOW_LATENCY`](https://developer.android.com/reference/android/media/AudioTrack#PERFORMANCE_MODE_LOW_LATENCY) was added in API 26, For API 24 or 25 use [`AudioAttributes.FLAG_LOW_LATENCY`](https://developer.android.com/reference/kotlin/android/media/AudioAttributes#flag_low_latency). That was deprecated but will still work with later APIs.
## Can I use Oboe to play compressed audio files, such as MP3 or AAC?
-Oboe only works with PCM data. It does not include any extraction or decoding classes. However, the [RhythmGame sample](https://github.com/google/oboe/tree/master/samples/RhythmGame) includes extractors for both NDK and FFmpeg.

## Android Studio doesn't find the Oboe symbols, how can I fix this?

Usually if you call `builder.setPerformanceMode(PerformanceMode::LowLatency)` and don't specify other stream properties you will get a `LowLatency` stream. The most common reasons for not receiving one are:
- You are opening an output stream and did not specify a **data callback**.
-- You requested a **sample** rate which does not match the audio device's native sample rate. For playback streams, this means the audio data you write into the stream must be resampled before it's sent to the audio device. For recording streams, the audio data must be resampled before you can read it. In both cases the resampling process (performed by the Android audio framework) adds latency and therefore providing a `LowLatency` stream is not possible. To avoid the resampler on API 26 and below you can specify a default value for the sample rate [as detailed here](https://github.com/google/oboe/blob/master/docs/GettingStarted.md#obtaining-optimal-latency). Or you can use the [new resampler](https://google.github.io/oboe/reference/classoboe_1_1_audio_stream_builder.html#af7d24a9ec975d430732151e5ee0d1027) in Oboe, which allows the lower level code to run at the optimal rate and provide lower latency.
-- If you request **AudioFormat::Float on an Input** stream before Android 9.0 then you will **not** get a FAST track. You need to either request AudioFormat::Int16 or [enable format conversion by Oboe](https://google.github.io/oboe/reference/classoboe_1_1_audio_stream_builder.html#a7ec5f427cd6fe55cb1ce536ff0cbb4d2).

- The audio **device** does not support `LowLatency` streams, for example Bluetooth.
-- You requested a **channel count** which is not supported natively by the audio device. On most devices and Android API levels it is possible to obtain a `LowLatency` stream for both mono and stereo, however, there are a few exceptions, some of which are listed [here](https://github.com/google/oboe/blob/master/docs/AndroidAudioHistory.md).

- The **maximum number** of `LowLatency` streams has been reached. This could be by your app, or by other apps. This is often caused by opening multiple playback streams for different "tracks". To avoid this open a single audio stream and perform
your own mixing in the app.
- You are on Android 7.0 or below and are receiving `PerformanceMode::None`. The ability to query the performance mode of a stream was added in Android 7.1 (Nougat MR1). Low latency streams (aka FAST tracks) _are available_ on Android 7.0 and below but there is no programmatic way of knowing whether yours is one.

-In Oboe, you can be notified of stream disconnection by overriding one of the `onError` methods in `AudioStreamErrorCallback`.

which is fired when a head set is plugged in or out. If your min SDK is LOLLIPOP or later then you can use [AudioManager.ACTION_HEADSET_PLUG](https://developer.android.com/reference/android/media/AudioManager#ACTION_HEADSET_PLUG) instead.

-<p>Output latency is the time it takes for a given frame to travel from the app to some type of digital-to-analog converter. If the DAC is external, for example in a USB interface or a TV connected by HDMI, then there may be additional latency that the Android device is unaware of.</p>
-<p>Input latency is the time it takes to a given frame to travel from an analog-to-digital converter (ADC) to the app.</p>

-<p>The latency of an INPUT stream will decrease abruptly when you read data from it and then increase slowly over time as more data arrives.</p>
-<p>The latency of an OUTPUT stream is generally higher than the INPUT latency because an app generally tries to keep the OUTPUT buffer full and the INPUT buffer empty.</p>

-<p>The caller should retain ownership of the object streamCallback points to. At first glance weak_ptr may seem like a good candidate for streamCallback as this implies temporary ownership. However, a weak_ptr can only be created from a shared_ptr. A shared_ptr incurs some performance overhead. The callback object is likely to be accessed every few milliseconds when the stream requires new data so this overhead is something we want to avoid.</p>

-<p>A buffer is ready for processing.</p>
-<p>For an output stream, this function should render and write numFrames of data in the stream's current data format to the audioData buffer.</p>
-<p>For an input stream, this function should read and process numFrames of data from the audioData buffer.</p>
-<p>The audio data is passed through the buffer. So do NOT call read() or write() on the stream that is making the callback.</p>
-<p>Note that numFrames can vary unless <a class="el" href="classoboe_1_1_audio_stream_builder.html#a3f397821f61eabaeedaf31064c859a54">AudioStreamBuilder::setFramesPerCallback()</a> is called.</p>
-<p>Also note that this callback function should be considered a "real-time" function. It must not do anything that could cause an unbounded delay because that can cause the audio to glitch or pop.</p>
-<p>These are things the function should NOT do: </p><ul>
-<li>
-allocate memory using, for example, malloc() or new </li>
-<li>
-any file operations such as opening, closing, reading or writing </li>
-<li>
-any network operations such as streaming </li>
-<li>
-use any mutexes or other synchronization primitives </li>
-<li>
-sleep </li>

-oboeStream->stop(), pause(), flush() or close() </li>

-oboeStream->read() </li>

-<p>This will be called before other <code>onError</code> methods when an error occurs on a stream, such as when the stream is disconnected.</p>
-<p>It can be used to override and customize the normal error processing. Use of this method is considered an advanced technique. It might, for example, be used if an app want to use a high level lock when closing and reopening a stream. Or it might be used when an app want to signal a management thread that handles all of the stream state.</p>
-<p>If this method returns false it indicates that the stream has *not been stopped and closed by the application. In this case it will be stopped by Oboe in the following way: <a class="el" href="classoboe_1_1_audio_stream_error_callback.html#a4eb1e4916b71d8231e97b19898bc9bf0">onErrorBeforeClose()</a> will be called, then the stream will be closed and <a class="el" href="classoboe_1_1_audio_stream_error_callback.html#a76bd3ef3e00396e10c21812003654cfe">onErrorAfterClose()</a> will be closed.</p>
-<p>If this method returns true it indicates that the stream <em>has</em> been stopped and closed by the application and Oboe will not do this. In that case, the app MUST stop() and close() the stream.</p>
-<p>This method will be called on a thread created by Oboe.</p>

-<div class="textblock"><p>On API 16 to 26 OpenSL ES will be used. When using OpenSL ES the optimal values for sampleRate and framesPerBurst are not known by the native code. On API 17+ these values should be obtained from the AudioManager using this code:</p>
-<pre><code>
-// Note that this technique only works for built-in speakers and headphones.
-AudioManager myAudioMgr = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
-String sampleRateStr = myAudioMgr.getProperty(AudioManager.PROPERTY_OUTPUT_SAMPLE_RATE);
-int defaultSampleRate = Integer.parseInt(sampleRateStr);
-String framesPerBurstStr = myAudioMgr.getProperty(AudioManager.PROPERTY_OUTPUT_FRAMES_PER_BUFFER);
-int defaultFramesPerBurst = Integer.parseInt(framesPerBurstStr);

-<p>A <a class="el" href="classoboe_1_1_result_with_value.html">ResultWithValue</a> can store both the result of an operation (either OK or an error) and a value.</p>
-<p>It has been designed for cases where the caller needs to know whether an operation succeeded and, if it did, a value which was obtained during the operation.</p>
-<p>For example, when reading from a stream the caller needs to know the result of the read operation and, if it was successful, how many frames were read. Note that <a class="el" href="classoboe_1_1_result_with_value.html">ResultWithValue</a> can be evaluated as a boolean so it's simple to check whether the result is OK.</p>
-<p><code> ResultWithValue<int32_t> resultOfRead = myStream.read(&buffer, numFrames, timeoutNanoseconds);</code></p>
-<p><code>if (resultOfRead) { LOGD("Frames read: %d", resultOfRead.value()); } else { LOGD("Error reading from stream: %s", resultOfRead.error()); } </code> </p>

-<p>A buffer is ready for processing.</p>

-<p>The audio data is passed through the buffer. So do NOT call read() or write() on the stream that is making the callback.</p>

-<p>These are things the function should NOT do: </p><ul>
-<li>
-allocate memory using, for example, malloc() or new </li>
-<li>
-any file operations such as opening, closing, reading or writing </li>

### Caveats
-When first time starting audio devices, the stream may not be stable.
-The symptom is the strange callback pattern. This sample waits half a second
-for audio system to stablize. It is an estimate, it would vary on different platforms.
+OpenES SL does not allow setting the recording or playback device.
+
+Synchronizing input and output streams for full-duplex operation is tricky.

+Input and output have different startup times. The input side may have to charge up the microphone circuit.
+Also the initial timing for the output callback may be bursty as it fills the buffer up.
+So when the output stream makes its first callback, the input buffer may be overflowing or empty or partially full.
+
+In order to get into sync we go through a few phases.
+
+* In Phase 1 we always drain the input buffer as much as possible, more than the output callback asks for. When we have done this for a while, we move to phase 2.
+* In Phase 2 we optionally skip reading the input once to allow it to fill up with one burst. This makes it less likely to underflow on future reads.
+* In Phase 3 we should be in a stable situation where the output is nearly full and the input is nearly empty. You should be able to run for hours like this with no glitches.

This sample demonstrates how to build a simple musical game. The objective of the game is to clap in time to a song by copying what you hear. You do this by listening to the clap sounds, then tapping on the screen to copy those claps.

The sample uses the following optimizations to obtain a low latency audio stream:
-- Performance mode set to [Low Latency](https://github.com/google/oboe/blob/master/FullGuide.md#setting-performance-mode)
-- Sharing mode set to [Exclusive](https://github.com/google/oboe/blob/master/FullGuide.md#sharing-mode)

+Soundboard
+==========
+Do you want to just jam with some digital tunes? Now you can!
+
+This sample demonstrates how to obtain the lowest latency and optimal computational throughput by:
+
+1) Leaving Oboe to choose the best default stream properties for the current device
+2) Setting performance mode to LowLatency
+3) Setting sharing mode to Exclusive
+4) Setting the buffer size to 2 bursts
+5) Using the `-Ofast` compiler optimization flag, even when building the `Debug` variant
+7) Using a `StabilizedCallback` which aims to spend a fixed percentage of the callback time to avoid CPU frequency scaling ([video explanation](https://www.youtube.com/watch?v=C0BPXZIvG-Q&feature=youtu.be&t=1158))
+
+The [following article explaining how to debug CPU performance problems](https://medium.com/@donturner/debugging-audio-glitches-on-android-ed10782f9c64) may also be useful when looking at this code.
+
+Implementation details
+---
+The stream properties are left to Oboe as such the app must output audio data in a format which matches that of the stream.
+
+Four different formats are supported:
+
+|Channel count|Format|
+|-------------|------|
+|1 - Mono|16-bit int|
+|2 - Stereo|16-bit int|
+|1 - Mono|Float|
+|2 - Stereo|Float|
+
+The signal chain for mono streams is:
+
+ SynthSound->Mixer
+
+For stereo chains a mono to stereo converter is added to the end of the chain:
+
+ SynthSound->Mixer->MonoToStereo
+
+The compiler optimization flag `-Ofast` can be found in [CMakeLists.txt](CMakeLists.txt).
+
+Each SynthSound is a series of 5 Oscillators, creating a pleasant sounding note when combined.
+
+There are 30 notes, corresponding to G3 to C6, moving left to right, top to bottom.
+
+In order to determine whether a note should be played, MusicTileView demonstrates how to keep track of where each finger is.

+# Minimal Oboe
+
+## Overview
+
+This app is a very simple demonstration of turning on audio from buttons.
+It uses a low-latency Oboe stream.
+
+## Implementation
+
+The app is written using Kotlin and Jetpack Compose.
+
+The app state is maintained by subclassing DefaultLifecycleObserver.
+Oboe is called through an external native function.
+
+This app uses shared_ptr for passing callbacks to Oboe.
+When the stream is disconnected, it starts a new stream.

For example, suppose you are converting from 44100 Hz to 48000 Hz and using an input buffer with 960 frames. If you calculate the number of output frames you get:

You cannot generate a fractional number of frames. So the resampler will sometimes generate 1044 frames and sometimes 1045 frames. On average it will generate 1044.897959 frames. The resampler stores the fraction internally and keeps track of when to consume or generate a frame.
