i use wavelab for every 'normal 'conversion
does batch job & has tick box for delete/overwrite original file
Mac or PC?? I STILL really miss Wavelab 3, it was the most awesome editor Ive ever used heh, did everything down to mastering my cd's in that one app. Moving to a Mac and Peak took quite a bit of getting used to and by the time I finally did, Peak is dead heh. Been using a combination of AudioFinder, Ocenaudio, Sound Studio and sometimes the MPC itself to edit stuff but maybe Ill check out Wavelab. I remember looking at the Mac version a few years ago and it not looking very familiar at all like I remembered. Its also called Wavelab Elements or something? I take it its a different version than the PC one??

here you'll find the differences between elements & pro

i use wavelab 6 on PC cause it gives me (mostly) all things that are now in the pro version

I never learned can Sox convert audio from 12bit to 16bit. I always worried how it would count those 12 bits on a 64 bit architecture.

Same, it was the best for sample edit and transfer.

Say, what happens to dither once it hits the not-so-ideal realtime sample rate conversion of a sampler?
Is there a chance that it would be less good than an undithered source?

And what about shaped dither when playing back a sample at a lower key? Wouldn't the distribution get messed up and become much more noticeable?

anyone has a 12-bit file to try? send me a link pls.

The same way it counts 12 bits on a 32 bit architecture.

That may sound like a snooty or snide answer, but as a programmer it's absolutely not a significant concern with regard to system architecture. The specific code and the assembly instructions it would get compiled to are very carefully described as to which bits are affected and in what way. One does, of course, have to be careful in a higher-level language to work in ways that are well-defined and not specified as having compiler-dependent implementations. (Bitfields in C, for one example, have no specifically defined packing order.)

I think the point was what do you do with the fewer or more bits? This is where noise shaping comes in.

Noise shaping is only for bit reduction tho. It's a way to distribute the dither energy.
But if you go from 12 to say 16 bits then you just don't have any information. I mean, you could guess what the new bits should be, but that has nothing to do with noise shaping.

I was gonna say, isn't the point of dither to add noise to cover up the bit REDUCTION? By upping the bitrate, youre not actually adding or taking away anything other than empty bits, there is no point to dithering.

Would you mind showing a SoX command line that converts wav data to 12 bit?

mind this :
Specifically, by default, SoX automatically adds TPDF dither when the output bit-depth is less than 24 and any of the following are true:

•bit-depth reduction has been specified explicitly using a command-line option
•the output file format supports only bit-depths lower than that of the input file format
•an effect has increased effective bit-depth within the internal processing chain

For example, adjusting volume with vol 0.25 requires two additional bits in which to losslessly store its results (since 0.25 decimal equals 0.01 binary). So if the input file bit-depth is 16, then SoX’s internal representation will utilise 18 bits after processing this volume change. In order to store the output at the same depth as the input, dithering is used to remove the additional bits.

command:
sox input.cdda −b 24 output.wav
converts raw CD digital audio (16-bit, signed-integer) to a 24-bit (signed-integer) ‘WAV’ file.

you request would than be:
sox input.wav -b 12 output.wav

remember:
Use the '-V' option on all your command lines. It makes SoX print out its idea of what is going on. '-V' is your friend.

Why wouldn't you just convert it to 12 bit straight from the cd itself?

… and you'll get:

sox WARN formats: wav can't encode to 12-bit

because bit width for wav files must be multiples of bytes (8/16/24/32 bits).
same for other formats using PCM method for storing information.

There is no such thing as -b switch with a value of 12. You must have used some other SoX option to convert to 12 bit.

I use this for when I'm prepping files for my MPC1000:

It's a really quick and dirty batch processor. It handles a few different function. Just avoid the actual tuning algorithm as it's not a very reliable algorithm.
