Small clicks between encoded chunks when concatenated about lamejs HOT 7 CLOSED

@geeee This worked, took us weeks to figure this out haha! Thank you very much for your help 🎉

from lamejs.

If anyone has done this sort of splitting up of a recording and encoding each chunk, and has a better way of doing this, that would be a massive help also. Just running out of ideas with this.

Hi. The code you provided looks fine as it is, so the problem might be elsewhere.
Do you reinitialize mp3encoder before each chunk is encoded?

from lamejs.

I do yeah, sorry I haven't shared that portion of the code, just above the for loop, where sample rate is 44100 and kbps is 128.

var mp3encoder = new lamejs.Mp3Encoder(2, sampleRate, kbps);

So for every chunk this is all initialised again as each chunk is encoded in a web worker, so all this is executed per chunk, but should be using the same info anyway.

(p.s. thank you for your response 😄 )

LAME adds silence to the start and the end of encoded mp3s. This might be the cause of the "clicks".
Try to use single Mp3Encoder instance to encode all of your wav chunks, flushing it only once at the very end.

Ok thanks so much, I'll give this a go 👍

Can some help me please?? Or could you give me an example please?
I use a single Mp3Encoder instance to encode all my wav chunks, and I flushing only once, but I have the problem yet. And sometimes part of the audio is repeated.

This is the encoded audio: https://clyp.it/dqsoux3a

This is my code: https://gist.github.com/mperezguendulain/3ef390647b274916618cfe0521a9f6bd

I'd really appreciate it if you'd help me.
