Batch SSRC
Are there any tools to do batch encoding with SSRC?
I have 7 albums that I need to do sample conversions with and a batch method would greatly cut down on the manual work. Last edited by EpheMeroN; 2nd August 2005 at 00:05. |

The new ww gives a message if clipping has occured, and in the list you can see which files clipped. I personally dont like it if programs do to much automaticaly. If clipping occured i would rather normalize it myself. But thats just me. I used to have this option (in an unreleased version) but since i didnt like it i also removed it again. Quote:
Im going to look into it, but if its to much work, il keep it on my todo for the next release. Currently im trying to support ac3encoding in cb, and when its finished, ill release a new ww.

What do you think is better, do a real two pass by first searching for the peak and then do the real conversion, or to do the second pass only when clipping is detected? Both are not to hard to do so..... its up to you

As I understand it, peaks that exceed 0dB may not be present in the source but can be produced by the conversion process. Therefore, searching for peaks before the conversion is pointless. Detecting peaks that exceed 0dB after conversion shouldn't be a problem as long as the data is in 32-bit floating point format.

What i was trying to explain are the following possiblities: -- convert it witout saving it, and look if clipping occured. If clipping occured the the amplification will be lowered a little, and then reconvert it and save it for real. This way you dont have to save the first time which improves the speed a little - same as before but with a large tempfile. This way the resampling doesnt have to be done again (if resampling was selected) --or just convert AND save it, and if clipping occured do everything again.

I am quite new to understanding how audio conversions work, and just audio in general so maybe someone can help me figure this out a bit. I was under the assumption that the --twopass option in SSRC auto-detects clipping and corrects it yes? Like if it clips at a certain part in the audio file, during the second pass it will lower it automatically so it will not clip. Now, if I want to use SSRC to go from 44100hz to 48000hz 'AND' also normalize all the cd's won't that leave me with another possible chance of clipping during the normalizing process? I'm just trying to find the best method of handling this. Finally, can WaveWizard decode MP3s to WAVE? Up until now I was going to use CDex to give me the WAVE files to start out with. I once read on the HydrogenAudio Forums that CDex performed really really well at decoding mp3s to waves.

Normalising to i.e. 95% is finding the highest peak, and change the overall volume so that the highest peak is at 95% of the max. So if you normalise there shouldnt be any clipping anyway. And if you are thinking about normalising, i wouldnt go above 95% just to be on the safeside. So if you normalise and resample at the same time in ww, there is never any clipping. About the mp3-decoding, ww once had this option, but when i released it, i removed it again. Im not to sure about the licensing stuff. But it still accepts mpeg audio files since i forgot to disable that to . So you can add them, but ww only creates an empty file when "converting" them. Doesnt cdex use uses the mpg123 lib? That is indeed a good decoder for mp3 (ww used it to), but according to the author the decoding of mp1+2 is a bit shaky. The lame decoder is also based on mpg123.

For decoding mp3's I highly recommend dBpowerAMP Music Converter (dMC). I've been using it for awhile and it works extremely well. You just right click on files and choose Convert then configure the options. It's free (there's an mp3 encoder that's trialware but decoding is free. dMC handles flac, ape and a whole variety of formats. Check it out at http://www.dbpoweramp.com/dmc.htm.

Er, well actually I voted for SSRC's twopass method as it is used in the program. I guess I just didn't say it clearly enough to be perceived as a vote. Ah well...
Is there any way you could at least put in a checkbox for those who want to use it the original way? |

Sure i can add it, but do you expect all files to clip? I mean if one in 10 files clip its faster to redo a single file then to do twopass on all of them. But ill add an extra radio button anyway . EDIT I just looked at it, and although its easy to do on normal file conversions, the "ssrc method" gives a little problem when merging files. So im afraid i have to push this to the next release since im trying to realease a new version asap. (hopefully today )
