Title: Transfer Problems
Post by: hzgone on October 23, 2003, 09:42:11 PM
Ok so i have my primus show all cleaned up from the clipping.  I edited it all in soundforge.  I split the tracks in cdwave and went to convert it using flac at 24/48 and i get unsupported file compression.  What gives?  Also if i downsample this to 44.1 i have to make it 16bit right?  Other than that if someone can help me out on the converting to flac or shn i think i might have this long process figured out.  To make things easier next time i think i'm just going to run 16/44.1

yes, if downsampling, you have to dither to 16 bit... 8)so you would end up w/ a 16/44.1k file... ;)

how did you clean up the clipping? and how bad was it?

You can have a 24 bit/44.1 KHz recording...

now, if the end result is CD quality, then you should resample and then dither, but if I understand the original question all he was asking was if I want to resample to 44.1 do I have to be in  the 16 bit realm and the answer is no... in fact, as I mention you should resample in 24 bit and then dither.

As for your Flac problem, I've noticed that, too... CDWave is spitting out the "new" WAV format which I'm guessing Flac cannot handle.  I recall reading about this on the CDWave FAQ... there are two slightly different flavors of WAV files now (the diffs have to do with the header) and the new version of CDWave went with the new style (microsoft's implementation).  WinAmp should still be able to play your WAVs, however Flac won't be able to compress them... you should however, be able to compress your original pre-CDWave-split 24 bit file without incident.

Hope this helps
Rusty

Here's a link to the CDWave FAQ that talks about the differences between the "old" 24 bit WAVs and the "new" microsoft way:


http://www.homepages.hetnet.nl/~mjmlooijmans/cdwave/faq.html#24bit


Also, it looks like CDWave 1.91 should have the ability to split to the old flac-compatible format.  Haven't tried it, but it looks promising:

"Write alternate 24-bit file format compatible with older programs "

I have a beta of the new CDwave that works find nad spits out the proper format for FLAC to use. PM me if you need it.

dither? I used soundforge to clean up the clipping, and it wsan't as bad as my first recording easy enough to clean up.

Is the upgrade from 1.73 to 1.91 needed/worth it if I am only doing 16/44.1?

it works fine for me compressing 24/48 wav files to flac after splitting them in cd wave.  make sure you have the latest versions of flac and cdwave.

i think he wanted to know what process you used to clean up the clipping and how severe it was in the original, ie. how many times did it clip or how distorted did it sound?

not really....here's a good description of dither i found through google
http://www.mtsu.edu/~dsmitche/rim420/reading/rim420_Dither.html (http://www.mtsu.edu/~dsmitche/rim420/reading/rim420_Dither.html)
dither is applied when doing a bit depth conversion from 24-bits to 16-bits in order to keep the recording sounding natural.
