How can I stream internal audio on Android?


Aside from using an intent to launch the sound recorder and using the MediaRecorder , Android offers a third method to capture audio, using a class called AudioRecord.

AudioRecord is the most flexible of the three methods in that it allows us access to the raw audio stream but has the least number of built-in capabilities, such as not automatically compressing the audio. The basics for using AudioRecord are straightforward. We simply need to construct an object of type AudioRecord, passing in various configuration parameters. The first value we'll need to specify is the audio source.

The values for use here are the same as we used for the MediaRecorder and are defined in MediaRecorder. Essentially this means that we have MediaRecorder. MIC available to us. MIC ;. The next value that we'll need to specify is the sample rate of the recording. This should be specified in Hz. As we know, the MediaRecorder samples audio at 8 kHz or 8, Hz. CD quality audio is typically Hz or hertz is the number of samples per second. Different Android handset hardware will be able to sample at different sample rates.

For our example application, we'll sample at 11, Hz, which is another commonly used sample rate. Next, we need to specify the number of channels of audio to capture. The constants for this parameter are specified in the AudioFormat class and are self-explanatory.

Following that, we need to specify the audio format. The possibilities here are also specified in the AudioFormat class. We can therefore set the resolution of each sample to be 16 bits or 8 bits. Sixteen bits will take up more space and processing power, while the representation of the audio will be closer to reality. Last, we'll need to specify the buffer size. We can actually ask the AudioRecord class what the minimum buffer size should be with a static method call, getMinBufferSize, passing in the sample rate, channel configuration, and audio format.

The AudioRecord class doesn't actually save the captured audio anywhere. We need to do that manually as the audio comes in. The first thing we'll probably want to do is record it to a file. Next we create an OutputStream to that file, specifically one wrapped in a BufferedOutputStream and a DataOutputStream for performance and convenience reasons. Now we can start the capture and write the audio samples to the file. We'll use an array of shorts to hold the audio we read from the AudioRecord object.

We'll make the array smaller than the buffer that the AudioRecord object has so that buffer won't fill up before we read it out. To make sure this array is smaller than the buffer size, we divide by 4.

The size of the buffer is in bytes and each short takes up 2 bytes, so dividing by 2 won't be enough. Dividing by 4 will make it so that this array is half the size of the AudioRecord object's internal buffer.

We simply call the startRecording method on the AudioRecord object to kick things off. After recording has started, we can construct a loop to continuously read from the AudioRecord object into our array of shorts and write that to the DataOutputStream for the file. Of course, in the real world, we wouldn't put this in a while true loop as it will never complete.

We also probably want to run this in some kind of thread so that it doesn't tie up the user interface and anything else we might want the application to do while recording. Before going through a full example, let's look at how we can play back audio as it is captured using the AudioRecord class. Android Developer Video Marketing current.
