Re: [MP3 ENCODER] Timeshifting after decoding

Is there a way to predict this timeshift? Does anyone know if it's a variable based on encoding or constant? It's because of the encoder delay. Now (3.90) Lame writes a kind of header into the first frame, and one of the fields of this header is the encoder delay.

Given that could a well written decoder strip it off and give time and length coherency between source and result? Yes, it's perfectly possible. However this tag is quite a new thing, and I think that right now there is no encoder that uses (yet) this info.

2001-12-04 Thread Ross Vandegrift
Hello all, I've noticed that encoding/decoding an mp3 introduces a timeshit. For example, encoding a 136,044 byte 44.1/16-bit WAV and then decoding and resampling gives a 136,074 byte 44.1/16-bit WAV. The surprising thing is that the extra data seems to be inserted at the
