Posted: Sun Nov 30, 2008 12:39 pm Post subject: Getting the best MP3 sound quality |
|
|
...how do you do it?
I've recorded a couple of files recently in AIFF, and there seems to be a noticeably better sound quality than MP3(which is recorded at 44,100, 16 bit, mono).
So would it be better to save in AIFF(or WAV) and then "dumb down" a copy to MP3?
Until recently I've been recording everything straight to MP3.
Just wondering. Obviously the only problem with recording exclusively in AIFF is the amount of space that format takes up compared to MP3.
The difference I hear could just be my imagination. It's not a life or death thing, but if I can improve sound quality in a way that's feasible, especially for clients, that would be a good thing.
Yes, I have searched the archives.  |

Rob,
No question uncompressed audio will sound better than compressed. I've added over a terabyte of hard drive space to my system so I do everything in WAV or AIFF format and convert down from there for the clients who want MP3 files. The only exception is that I'll do auditions directly to MP3.
Then I back everything up to an external hard drive every evening and archive to Data DVDs ever few weeks as a further back-up. _________________ Be well,

I record and edit in AIFF and convert from there.
Disc space shouldn't be an issue! Hard drives are so inexpensive these days. _________________ DBCooperVO.com

Always work in the best source possible, uncompressed wav or AIFF. Heck that's what I deliver to my clients as well. _________________ Jeff

Yep.
I record in 16bit 44.1K .wav and convert to whatever file my clients want from there.

A lot of my clients ask for 48 kHz 16 bit .AIFF, so I often record 48/16.
It's also good to record at 24 bit if your computer handles it nicely and if the down conversions work well. A lot of VST plugins and other processing (if you're doing that) work better if you just keep it simple at 16 bit.
Audition offers 32 bit and 16 bit recording options. Don't select 32 bit if you have a 24 bit soundcard as many people (like me) do. It's forcing a lot of digital water into a smaller digital funnel and it sounds like swill. _________________ Skype: globalvoiceover

I always ask beforehand what the audio will be used for. If for video, it is my experience that 9 out of 10 times they need 48K... on my PTHD rig I have been recording @96k/24bit for years now and I'm very happy with the results. I've had no complaints ever, not even from the very serious gearheads... never had any flaws in converting down to 48/16 or 44.1/16. When on PT LE I almost always record in 44.1/16 and master to uncompressed WAV-files. For the rest... what Liz said.

24 bit/48kHz recording and then I bounce using $20 Pro Tools Mp3 option and it sounds great always. It seems to sound a shade better than the iTunes mp3 conversion that I used to do way back when. _________________ Ben

All because the Digidesign MP3 Option uses a customized professional version of the Fraunhofer encoder/decoder. The team of engineers at the Fraunhofer Institute were the guys that actually founded the MP3 standard back then. Their encoders, together with "LAME" are the best MP3-encoders available today IMHO.
EDIT
@Ben: I assume you use a dithering plug-in on your masterfader when bouncing to MP3 Option? |

I record in the 44100 stereo 32 bit float and then when I save, I save as mp3 at 192 Kbps instead of the 128. My daily news get put on over broadcast stations with nary a complaint. _________________ Does life start at 40? |

Like all the rest of the smart people here, uncompressed then exported to the format the customer wants. With storage space so cheap, really no reason not to do it this way. _________________ Try to imagine a world where there is no such thing as hypothetical situations.
