Hi
What am I doing wrong?
I get this error when I click preview:

Soundshaper CDP Error. Preview Not possible .Ok
ERROR: INVALID DATA
ERROR: Can't open file ~X_-1.wav to read data.

Hi Robert!
A lot of thanks for your help and for creating this awesome and creative software.
I don't know what the structure of the text file should look like?

C1 32.70 Hz
C#/Db1 34.65 Hz
D1 36.71 Hz

I think you're referring to CDP's FILTER BANK 6, which tunes filters in equal intervals of so-many semitones. I would expect these to be in equal temperament (though the CDP documentation doesn't clarify this). If they were in just intervals, you could soon end up with some pretty "unjust" tunings: for example 3 equal-tempered thirds coincide with the octave, whereas 3 just 3rds piled up give slightly less (125/64 = 1.953125 instead of 2.0).

If you want to set your own frequencies, check out FILTER VARIBANK, which uses a text table of frequencies (or MIDI notes) and amps. You can easily load a text file of frequencies tuned to whatever you want. This is one of CDP's most powerful tools (in my opinion), and it's time-varying.

Hi,
Yes, the search function in SoundThread (typing in name) is very clever - I haven't a clue how this is done, so I'm afraid it's not in Soundshaper.
* * * * *
Frequency Shift is called Strange Shift in CDP, documented under Spectral. (https://www.composersdesktop.com/docs/html/cstrange.htm#SHIFT)

It's in the Soundshaper Menu: Spectral > Pitch/Frequency > Shift > Shift Frequencies, grouped with the related functions from Specfnu (so Spectral > Pitch/Frequency > Shift > Shift / replace with formants) i.e. specfnu modes 13, 14 and 19. (https://www.composersdesktop.com/docs/html/cspecfnu.htm#FREQSHIFT etc., see mode list on left)

All these functions can unfortunately produce unwanted artefacts (depending on the source and settings). This seems especially true of Specfnu (which was probably geared towards speech). I understand that the wavelet transform is cleaner than PVOC in this respect, but that is not available in CDP.

Process Table:
Thanks for reporting the missing Process Table for 'Data' - I'll fix the link in the next version. I personally never use these tables and wonder if they're used at all. Any thoughts on this from users would be welcome.

Hello,
That's correct. You will lose the 6.4 added functionality for a time (until I re-construct it) but hopefully you will not have these patch-loading problems now. But I will be checking all these aspects very carefully, which is why I felt a temporary downgrade was better than attempting a quick fix. The missing functionality is 1) no balance option in Previews 2) some changes to Loading patches, especially when the saved source is not included / or no source has been saved.

General Board / Equal intervals 2

Hi
In soundfile-Filter- Equal intervals 2 (Low Freq-High Freq) bands defined by interval size, the interval semitones created are tuned in equal-temperament or in just intonation?

Sorry to "bump" this, but is there anything I could try?

Also that alternative .exe for an old version that was mention on Mr. Wishart's website isn't available anymore (gave me 404 response).

While I'm feeling comfortable with SoundShaper and SoundThread, I hope to try SoundLoom, too, at some point in the future.

Thanks, and best wishes!

General Board / About CDP programs and GUI(s)
Last post by Vasilakis - June 06, 2025, 06:27:26 PM
Hi,

I don't know if there was already a thread about it, but I wanted to ask... Is "SPECFNU" presented only as CMD command, or it's also in SoundShaper as well (I looked in Formants submenu, but didn't find such)? Same question for "STRANGE" functions.

Why I am asking about those, it's that I was trying to see which functions in CDP can do frequency shifting effects, and I've seen those mentioned above in documentation.

One thing I liked in the recently released SoundThread GUI, you can open up a "search" and start inputting names of programs. Is it also possible in other GUIs? Just curious.

By the way, "process table" button in SoundShaper works for me in all menus except "data" (just mentioning in case you've missed this).

Thanks, and have a nice day!

Hello again,

Glad to hear that the situation became clear.

Meanwhile, do I understand it right that it would be enough to replace .exe to make downgrade from 6.4 to 6.3?

Thanks

Hi,
I tried your patch in Soundshaper 6.4 and 6.3. There were two issues. In 6.4, the patch didn't load all the files, so it didn't have the necessary parameter files (.prm). I may have changed the way these files were copied; I'll need to check the coding here. In 6.3 it loaded fine, but failed on FLTVARI and the 2nd SPEED, because the subfolders A_3 and A_4, which should have contained their .brk files, were empty. Again this may be caused by changes in the the way files were copied. They were altered to accommodate running Soundshaper under WINE and appeared to work at the time, but were probably not fully tested. I'll be looking into this more fully before releasing another version. I'm sorry you've had such a bother with this issue, but you've helped to unearth some bugs and I'm very grateful for this.
Robert
