[Audacity-nyquist] Clip Fix Issues

[Eric B. <bel...@gm...>]

I updated to the newest version of Audacity, but in doing so I have found
that there is a new version of Clip Fix. I run a Dungeons and Dragons
podcast and previously I could set the threshold to 100% and it would get
rid of the very loud dice rolls throughout the recording. However, with the
new version I am having trouble doing this as there is a new option that
states “Reduce amplitude to allow…”

It seems with this change, now when I go to do clip fix with even the
default settings, it drastically lowers the volume of my recordings.
Previously, the clip fix would simply lower the dice rolls without
affecting the rest of the audio.

Any ideas on how to help with this or if I could install an older version
of clip fix and use that instead in Audacity?

Thank you for your time.

Re: [Audacity-nyquist] Question Input voice

[Roger D. <rb...@cs...>]

I think Nyquist could be good for prototyping, but a convenient app 
that's easy to use will probably require something independent.

Carnegie Speech has some interesting products for language learning.

[Audacity-nyquist] Question Input voice

[Helena W. <hel...@ho...>]

We are developing a speech training tool :
 
EX: Say this Word with gentle onsets: "orange"
 
Feedback: Voice-curves, where you get visual feedback of your speech, level of fading in and out. 
 
The solution needs in signal processing is detecting the right algorithm for
fading in - fading out of the input voice. (Gentle onsets)
 
Could this be done in audacity-nyquist programming? In that case, which option should we use?

Hello,

I m trying to add an option of determining the tempo i.e. Beats Per Minute
for a music clip. For that i am using Nyquist coding. I need guidance with
the Nyquist coding. Can you please provide me with a proper manual which

Hoping for a support as soon as possible.
Thanks in advance.

Re: [Audacity-nyquist] building a plug-in that removes instruments

[Roger D. <rb...@cs...>]

Hi Scott,
     I *did* read the post but was traveling at the time and wasn't even 
sure how to answer. You should be clear what your problem is, e.g. is 
this a DSP question, a user interface question, a Nyquist question, or 
an Audacity question. In the context of "Audacity-nyquist"  I would 
expect a nyquist question, but you haven't said what you are trying to 
get Nyquist to do. (If the answer is "remove instruments", this is a 
signal processing question, not a Nyquist question.)

Hi Leland,

I think you must have an old menus.cpp there. 

The removal was committed here:
http://code.google.com/p/audacity/source/detail?r=12510 

and it's still removed in Menus.cpp in HEAD.

No more posts for six months. 

I suggest closing this list unless someone strongly objects. We can 
point to the Nabble archive from the Forum. There are splendid 
Nyquist discussions on the Forum, and all the new plug-ins are 
there.

Yes this is 32-bit Debian Squeeze.

Profiling to see where the time is going sounds like a good approach but
sadly I'm not a programmer and I've no idea how to do that.

Of course, the standalone runt ime should match the Audacity runtime, at 
least in this case, where there's no substantial interaction with 
anything outside of XLISP. So now we have 2 disparities to resolve. I 
think the next step is profiling under Debian to see where the time is 
going. I assume everything here is compiled for 32 bit architectures. 
There might be a big difference between running 64-bit vs 32-bit code 
(not to mention that Nyquist doesn't support 32 bit code -- but actually 
the latest version in SVN is running under 64-bit OS X and I'm in the 
process of testing others.)

Standalone Nyquist in Debian:

(defun test ()
(dotimes (i 10000000)
(setq x i))
(print "done"))

{note: this counts to 10,000,000}
about 6 seconds - counting to 1,000,000 was too fast to time, about half a
second.

This is a great test because there's no signal processing. What happens 
here is:
     memory allocation and garbage collection (all but small integers go 
on the heap)
     occasional calls to oscheck() to check for interrupts
It's possible, depending on compilers and alignment, that XLISP cells 
are bigger on Debian.
It would be really helpful to profile the code. Also, it would be 
interesting to run the same in nyquist on both systems (not within 
audacity).

but it's not.
Running the following in the Nyquist Prompt effect:

(dotimes (i 10000000)
(setq x i))
"done"

Windows XP Guest in Virtualbox: about 2.5 seconds.
Debian host: about 12 seconds.

I thought so too, but here we are.

The speed of Nyquist should be very similar on both. One big performance 
issue I've run into is that any signal that decays (exponential 
envelopes, feedback delay, reverb) eventually becomes denormalized, and 
depending on how things were compiled, the cpu, etc., this can invoke a 
software handler at which point floating point becomes VERY slow. I 
should probably make a simple test to see if this is happening. It would 
also make sense to make some simple tests to see if the speed difference 
is related to allocation, floating point, the XLISP interpreter, etc.

I thought this list was closing?

Is it possible to compare the Nyquist IDE (rather than Audacity-Nyquist)
on the two platforms? Is the result the same?
