This is a simple Audio Resampler using Oboe Resampler in order to change Channel and SampleRate.

• Add to dependencies

implementation("io.github.nailik:androidresampler:0.3")

• create the Configuration with input and output settings.

val configuration = ResamplerConfiguration(
    quality = ResamplerQuality.BEST,
    inputChannel = ResamplerChannel.STEREO,
    inputSampleRate = 441800,
    outputChannel = ResamplerChannel.MONO,
    outputSampleRate = 16000
)

• create the resampler, this also creates the OboeAudioProcessor

val resampler = Resampler(configuration)

• to convert audio send in a ByteArray and you get back a ByteArray
• Note: in case of same input and output configuration the input ByteArray is just send back directly

val data: ByteArray = resampler.resample(recordedAudio)

• dispose the resampler when finished, note it cannot be used anymore afterwards
• isDisposed can be used to check if resampler was disposed already

resampler.dispose()
val isDisposed = resampler.isDisposed
