android - Between AudioTrack.write and AudioFlinger.read

Question

I am checking the possibility of this way, if I got any silly thinking, please correct me. I would like to enhance the audio quality. According to some knowledge from web, I found that When an audio/music/sound is played , the AudioTrack will write() PCM data to the sharedbuffer, and then AudioFlinger will read() the PCM data form this sharedbuffer. The idea is to use a service to intercept the PCM data after it is wrote by AudioTrack.write(), modify the PCM data, and then restore it back to the sharedbuffer for AudioFlinger to read(); Could anyone help/correct me, please?

Answer 1

我不太了解 AudioFlinger，但是要读取 PCM 数据，您可以使用 AudioRecord 并写入 PCM 数据，您可以使用 AUdioTrack 播放声音。
