Help with fixing a poor quality interview

I've been given an audio cassette from which I have captured in an interview a friend of mine recorded back in the early 90s on one of those very cheap Dictaphone type recorders. The sound is muffled, with background rumble throughout, and seemingly no "top end" at all. Is there any hope for fixing ...

Re: Re-Timing AC3 audio

I have been supplied with audio files (ac3 and dts) that were encoded in the US and subsequently used on a US 23.98fps (progressive) DVD.

Re: Re-Timing AC3 audio

Thanks for your help!

PAL (25 fps) = 102m 53s (the NTSC needs to match this)

NTSC (23.976 fps) = 107m 25s

I don't know if this is of any use?

Re: Re-Timing AC3 audio

Re-Timing AC3 audio

Hi all,

My first post.

I have some .ac3 and .dts encoded files which were supplied to me at 23.98 fps - which I need to re-time to PAL 25 fps. Is it possible to do this with Audacity?
