How to set delay with out re-encoding.

[#2]

Please excuse the basic nature of this Question. I've been searching for the last 3hr trying to find how to adjust a delay in a mp3 track with out re-encoding it. When I use the payload option in Bsweet I end up with a mp2 file with a loud hum at the begining of it. I'm sure this must be simple. Can someone point me in the right direction please.

you don't add the delay to mp3 itself
you specify it when muxing it to the video

Thank You Sir.

I know the mxing tools alow you to do this. And Bsweet also has a sting for delay. Just wondering if it can set delay with out re-encoding eg besweet -core (in out) -ota (delay)? When I do this it gives me the default mp3 128kbs re-encode.

Is this possible?

Thanks again.

From my point of view, delays are set when you want to fix sync of an audio track to something else, namely a video track. And that is accomplished thru muxing. Why else would you need a delay for?

Still keen to know if it is possible with Besweet. Dose any one know?

there is a program called ac3delaycorrector, but it's for ac3
you could use besplit fornegative delays (just cut the delay time of)
for a positive delay you'd have to add silence (make a silent file and use besplit to add it)

[DSPguru]

currently, loseless delay assertion is only possible for mp2 and ac3.
for adding delay to mp3 i can now advise you to use BeSplit to cut the beginning of your mp3 file at the desired delay length, and then join it to your original stream.

Thank you DSPguru and E-Male : )
