Sample rate 8k, downsampling

[tehmaestro]

Hi, thank you very much for your sample. One question though, is there any way I can encode the WAV at 16 bit PCM 8k sample rate? I know AudioContext doesn't allow to change the sample rate, but is there any other way of doing this?

I'm asking because the files are pretty large as it is right now, and I'm trying to send the WAV to the server, thus I'm trying to save the users a lot of bandwidth.
Thank you very much. Any idea would help.
