2. There is no Java Sound API on Android. 1. Use AudioRecord to record the audio to a buffer and calculate the noise level(incoming decibels to the mic) from the raw PCM data. Don't forget to bypass the noise cancellation feature, if you need the surrounding noise.
// Initialise the AudioRecord AudioRecord record = new AudioRecord(AudioSource.MIC, SAMPLING_RATE, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, bufferSize); // Read a sample from MIC short[] buff = new short[8000]; record.read(buff, 0, buff.length); On 20 янв, 19:58, manas gajare <[email protected]> wrote: > 1.
