The solution from Toumal works, however I wasn’t able to get a high enough refresh rate for my needs. So I ended up using the SoundMeter.java class that Toumal linked but modified it to use the code from this answer Here is the code I used, which provides a much better refresh rate: import android.media.AudioFormat; … Read more
As I understand you don’t want any automatic adjustments, only manual from the UI. There is no built-in functionality for this in Android, instead you have to modify your data manually. Suppose you use read (short[] audioData, int offsetInShorts, int sizeInShorts) for reading the stream. So you should just do something like this: float gain … Read more
The original poster has probably long since moved on, but I’ll post this in case anyone else finds this question. Unfortunately, in my experience, each device can support different sample rates. The only sure way of knowing what sample rates a device supports is to test them individually by checking the result of AudioRecord.getMinBufferSize() is … Read more
Webrtc is considered as comparatively much better pre-processing tool for Audio and Video. Webrtc native development includes fully optimized native C and C++ classes, In order to maintain wonderful Speech Quality and Intelligibility of audio and video which is quite interesting. Visit Reference Link: https://github.com/jitsi/webrtc/tree/master/examples regularly. As Problem states; I want to record but smaller … Read more
Here I am posting you the some code example which record good quality of sound using AudioRecord API. Note: If you use in emulator the sound quality will not much good because we are using sample rate 8k which only supports in emulator. In device use sample rate to 44.1k for better quality. public class … Read more
The trick with using AudioRecord is that each device may have different initialization settings, so you will have to create a method that loops over all possible combinations of bit rates, encoding, etc. private static int[] mSampleRates = new int[] { 8000, 11025, 22050, 44100 }; public AudioRecord findAudioRecord() { for (int rate : mSampleRates) … Read more
