1-Bit Wave File?
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. |

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? |

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 . . . . . . . . ... . . . . . .

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. Fans of the Atari 2600 sound chip TIA beg to differ Each of itsvoices 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 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 . . . . . . . . ... . . . . . .

Hey Tachyon, So you're assuming that the OP wants to do this in order to implement some sort of musical effect? An interesting possibility. My question was intended to be taken at face value. I was asking about the OP's intention, not implying that one shouldn't do such a thing. My gut feeling is that he wanted to create a 1-bit delta sigma bitstream (which won't happen if you merely convert to a 1-bit stream), but I don't really know. That's why I asked. rock and roll, -N Hey Tachyon, nice screen name.
