![]() First you should place opus.aar in the libs folder of your project and then add to your build. opus.aar - it's a compiled library of opus module that mentioned above, it placed in a root directory of the project, you can easily add it to your project using gradle dependencies. THE OFFICIAL OPUS 1 THREAD: iDEN + Android 'Opus 1' HowardForums is a discussion board dedicated to mobile phones with over 1,000,000 members and growing For your convenience HowardForums is divided into 7 main sections marketplace, phone manufacturers, carriers, smartphones/PDAs, general phone discussion, buy sell trade and general.opus - here you can find a C++ class that interacts with libopus 1.3.1 and a JNI wrapper for interacting with it from Java/Kotlin layer.I recommend to check this app using a headphones, otherwise there may be echo in a hight levels of volume. app - here you can find a sample app that demonsrates ecoding, decoding and converting procedures by capturing an audio from device's mic and play it from a loud speaker.If (encoded != null) Log.d("Opus", "encoded chunk size: $") Freeing resources when closing the app: codec.encoderRelease()ĬcoderRelease() Project structure The project consists of two modules: Val encoded = codec.encode(frame, FRAME_SIZE) // encode a chunk of audio into Opus gets a chunk of audio from some source as an array of bytes or shorts Val BITRATE = () // encoder's bitrateĬodec.encoderSetComplexity(COMPLEXITY) // set the complexityĬodec.encoderSetBitrate(BITRATE) // set the bitrate Encoding: val frame =. Val COMPLEXITY = (10) // encoder's algorithmic complexity Val codec = Opus() // getting an instance of CodecĬodec.encoderInit(SAMPLE_RATE, CHANNELS, APPLICATION) // init encoderĬcoderInit(SAMPLE_RATE, CHANNELS) // init decoder Setup the encoder: /* this step is optional because the encoder can use default values */ ![]() Var FRAME_SIZE = Constants.FrameSize._120() // default frame size for 48000Hz Val APPLICATION = () // coding mode of the encoder Val CHANNELS = () // type of the input audio mono or stereo Convert from bytes to shorts and vice versa.Īrmeabi-v7a, arm64-v8a, x86, x86_64 How to use Init encoder and decoder: val SAMPLE_RATE = Constants.SampleRate._48000() // samlpe rate of the input audio.Sample rate of input audio from 8000Hz to 48000Hz.An android wrapper around libopus 1.3.1 written on C++ and Kotlin.
