Inconsistent buffer size upon decode?

[kanatliemre]

I'm using the encoder with the web audio api to encode 16384 sample long buffers, then I convert them to ArrayBuffers and send to another computer via nodeJS. However when I decode these ArrayBuffers using audioContext.decodeAudioData() the resulting audioBuffer I get varies in sample size, for silent audio it becomes 16960 samples long. This problem causes glitchy audio at the other end.

Any idea what might be causing this? or is my encode/decode strategy wrong?

This also happens to me, did you find a way around it?
