Fixing mp3 44.1 to 48k
Hi,
I have a long (8 hour) mp3 that is too slow by the ratio 44.1/48 due to an error editing the source material. What is the best way to speed up this mp3? Cheers, Gareth. |

Try http://www.voxengo.com/product/r8brain/ You can easily change file sample rate Vs playback rate. Many DAW's will do this also, but I'll assume yours doesn't or you probably wouldn't ask.

Was trying all sorts of stuff last night but it wasn't doing what I wanted. (Rendering to WAV only resulted in a 28 minute file) Cheers, Gareth. |

Your editing software probably has a function which allows you to change the sample rate in the file without actually resampling the data. That is what I'd do. --scott -- "C'est un Nagra.

(Rendering to WAV only resulted in a 28 minute file) 8 hours to a .wav ... some software gives up at 2 gigabytes. Or at 4 gigabytes, beyond that only broadcast wave applies. Stereo or mono? Gareth.

Easy enough to split an mp3 into one hour segments in just about any DAW without quality loss. -- Tciao for Now! John. |

Got caught up trying to render to WAV and then re-importing. Just wouldn't render to WAV. Gareth. |

Or at 4 gigabytes, beyond that only broadcast wave applies. Stereo or mono? Gareth. Kind regards Peter Larsen I usually record Stereo WAV, about 10Gb per 8 hours. Adobe Audition splits it into 3 x 4Gb/4Gb/ 2Gb WAVs with no losses at all. I stitch them together in Wavelab6 (montage mode) then render to mp3. Not usually any problems at all. Wasn't able to record on the laptop on this occasion but got a direct to mp3 on a USB stick recording from the Yamaha LS9 instead. At least I got a recording. It was converting this to WAVs that wouldn't work properly, and I messed up the sampling rates as well converting to RAW/PCM instead. Turned out the Wavelab montage can just be switched to run at a different rate without changing any data at all. Cheers, Gareth. |
