Re: [PD] what happens when you send signals between 0..1 instead -1..1 to dac?

2020-03-01 Thread Lucas Cordiviola
 I guess there's a math foundation here that would justify the need for a -1..1 correct signal range... Is just a convenience. 16bit or 24bit audio files have totally different numbers to represent the start, middle and end of the same sine wave. Why would you want Pd to have 0 as one side

I think the DAC/audiobackend/soundcard will accept those values "As is". The Amp and the Speaker will just work on "one half" of their normal area. (50% of its audio loudness). It shouldn't hurt the amp or the speaker as long as you don't try to pump up the volume. You might break the

Hi, software like Pd or jack doesn't care because it's not forbidden to send only positive or even constant values. You might use your DAC to send control voltages for a modular synthesizer, for example. Most audio interfaces, however, apply some kind of highpass filter to the outputs to get

Hi everyone, I just found out that I have sent signals between 0..1 instead of -1..1 to [dac] (!!!), and I am wondering... what happens in that case? Does Pd take care of that in any way? Or, Is that the job of portaudio/asio/jack? Or, Is that the job of the audio interface? Or, nothing happens

[PD] sigmund~ track analysis errors

2020-03-01 Thread João Pais
Hi list, Related to the bug report https://github.com/pure-data/pure-data/issues/872 , I wanted to drop some questions about sigmund: - when using the "-npeak x tracks" settings, the X stands for the maximum number of tracks, and no more are allowed. Is this the expected behavior? It's not
