1-Bit Wave File?

Started by Curious May 16, 2004
I am looking for audio software that allows conversion of 16-bit WAVs
and 8-bit WAVs to 1-bit WAVs. I have used Adobe Audition and CakeWalk
Pyro. Neither of them work. CakeWalk does have a "bit-depth converter"
as a FX, however, when I try to use it, I get a runtime error and
Cakewalk automatically closes.

Why do you want to convert to a 1-bit WAV? -- % Randy Yates % "Maybe one day I'll feel her cold embrace, %% Fuquay-Varina, NC % and kiss her interface, %%% 919-577-9882 % til then, I'll leave her alone." %%%% <yates@ieee.org> % 'Yours Truly, 2095', *Time*, ELO http://home.earthlink.net/~yatescr

The wave editor in Magix's mp3 maker can do that. But all you get is noise. Do you understand what bit depth is all about? Abbedd

Do you really want a 1-bit on/off signal or did you mean to ask about 1-bit delta sigma modulation?

The software in the Roland SP-808 lets you do this...in real time, even. You use a knob to select the number of bits. Plus, it lets you adjust the sample rate and even whether or not you want the noise-shaping filter turned on! p.s. I found this link on Randy Yates' page about noise-shaping... http://home.earthlink.net/~yatescr/noiseb.ps I think a line from that paper may answer Randy's question about WHY you want to do this: "...quantisation of highly correlated signals (such as music) results in tonal distortion components being added to the signal." rock and roll, -N -- different MP3 every day! http://gweep.net/~shifty/snackmaster . . . . . . . . ... . . . . . .

A little understanding can be a dangerous thing. With a 1 bit PCM data stream, there is effectively no recogisable signal. I think Randy may have been talking about bit-depths down to around 8 bits. However even this quanisation noise is not a type of distortion that is likely to sound in any way pleasant in pretty much any style of music. geoff

Even with 1 bit, if properly dithered, you should be able to recognize the signal, though it will be buried in noise. I'm wondering the OP wants to convert to some type of SACD (1-bit but very high SR) format?

Fans of the Atari 2600 sound chip TIA beg to differ :) Each of its voices is capable of about 6 unique waveforms, each of which is a train of 0's and 1's. Additionally, square and PWM waveforms, staples of much electronic music, are 1-bit waveforms. Curiously enough, the TIA can't quite make 50% duty cycle square waves, but several close matches, like 15/31 :) -- different MP3 every day! http://gweep.net/~shifty/snackmaster . . . . . . . . ... . . . . . .

That's all gobbledygook for all the OP cares. He wants to CONVERT .wav files to 1-bit form. Either he knows why he wants it, or he doesn't know what he wants. Either way, talk of TIA and PWM won't help him.

Hey man, I'm just sticking up for 1-bit waveforms! -- different MP3 every day! http://gweep.net/~shifty/snackmaster . . . . . . . . ... . . . . . . "Maybe if you ever picked up a goddamn keyboard | Niente and compiler, you'd know yourself." -Matthew 7:1 | shifty@gweep.net
