Hello Simone. What problems have you been facing with AudioTrack?
Besides the fact that you will need to handle all the overhead of time/ streams controling everything should work fine with AudioTrack, even using the Emulator. For the volume change for example, try to each position of your audio streams for a float between 0.0f (no sound) and 1.0f (volume at 100%) and cast back to short before playing. Should give you the results you want. For the SampleRate, once AudioTrack is created you cannot change it´s samplerate value, but you can upsample/downsample your streams to get the desired efect. Hope it helps, Gabriel On 23 mar, 17:57, Simone <simone.russ...@gmail.com> wrote: > Hi everyone, I'll try to explain briefly what I need to do. > I need to load an audio resource and play it, but I also need to be > able to modify some parameters (like the volume, or the playback rate) > while the audio is being played. > For example, I might want to play a 10 seconds audio stream, and > change the volume only after 3 seconds. > Is there a way to do it?
