I read that best way to mix multiple audio PCM samples is to take the average of the samples each frame. So if I am adding together say 5 16 bit samples before dividing by 5, there is obviously a good chance it will have a value greater than a 16bit short can hold. So when mixing together multiple 16 bit samples, do I store them all in int first and add them and …

Let's come back to our problem: two PCM audio sources, based on same prototype, audio1 and audio2 need to be mixed into audio3 ; short *audio1, *audio2, *audio3; of course the size of audio3 will be the same as audio1 (and audio2) since the music will be at the same speed :) 44100Hz...

PCM audio manipulation - volume control and mixing Can anyone point me to some guidance or software to manipulate PCM audio using a dsPIC33EP512MU810 ? I want to increase/decrease the volume of the PCM data and also mix it with some pre-stored short audio clips. The dsPIC is receiving PCM via I2S from a bluetooth module (WT32i), which I then ...

But after mixing, the audio is totally noisy. When audition is turned on, it is found that the amplitude is very large, presumably causing an overflow. The first audio waveform: The second audio waveform: Mixed audio waveform: All the above audio files are opened in little-edian mode. No problem with the first and second audio playback.
