How to smooth audio playback from audio input plugin

0 votes
HI,

I am writing an audio input plugin to play audio from an in memory buffer (it is is the audio stream of a .mp4 video being decoded elsewhere in the program). I have managed to register this plugin, and written the mandatory callbacks for GetFormat and Execute callback.

The decoded audio stream in 16 bit fixed point interleaved integer for a dual channel stereo format. which I set using AkChannelConfig::SetStandard to create a configuration and then call AkAudioFormat::SetAll tp set the remaining format values.

In the ExecuteCallback function I get the MaxFrames vlaue for the io_outbuffer object and copy that amount of data into the buffer, before setting uValid frames to MaxFrames and eState - AK_Dataready.

This results in the audio being played, and matching with the video. However it is not smoothed containing sharp 'tick' sounding noises which I suspect are small bursts of static at seemingly regular intervals.

Can anybody assist in how to achieve smooth audio playback via this source plugin?
