Re: Possible noise issue in EQ A2.0.3
How big is the amplitude of the modified silences (sorry, I can't see the graphics myself)? If the disturbance is rather tiny, I can offer the following explanation: The eq effect is built up with several Filters. They are most likely so called IIRs (infinite impulse response). As the name implies, ...

Re: Possible noise issue in EQ A2.0.3
Maybe it is dithering noise, that's boossted?

Re: usefullness of envelope tool
I would take an graphics design tool approach to implement the linear functionality: You simply switch the line behaviour by a secondary click on the envelope point and so the line to the nearest point to the left will change into a linear one. A secondary click will reset it to a exponential charac...

Re: Using "select-all" just for audio
You're right, it is rather queer. I don't know why Audacity passes short sounds to the effect, as if they would have the same duration as the longest one. I guess that it simplifies the code execution. I can only talk for Nyquist effects. If I want to write a really multi-track selection suitable pl...

Re: REQ: R1 MF ("Blue box") Tone Generator
Perhaps I won't need these tones myself. Nevertheless it's an interesting task, so I gave it a try too. I've been playing with some recursive code (loops get boring over time). I only wanted to contribute some code for the sorting out of the text input but ended up with nearly the whole plug-in. The...

Re: How to compute SPL from sound inputed from a microphone.
Hi Koz Have I missed something? What are you refering to? Taking the rms of a single point does never make any sense, neither analog nor digital. However, the Rms for a complex (i.e. complicated) waveform is straightforward and really easy implemented. There are 4 types of RMS which are facetiously ...

Re: Beginner's question
There's still a great deal of misunderstanding, I am afraid. Please forget your previous code examples, they do not fit into the conventions of the pan command. Especially the strange scale factor of (/ 1 0.697522). Can you please explain why do you insist on this value? It is simply too big, as it ...

Re: Beginner's question
Hello Sirs. I thank the moderators for their help. On the other hand, I am sorry, I did not understand the end of Robert J.H.'s message. "...multiply by 0.5. The lfo goes now from -0.5 to 0.5..." It is the function [(sum] which multiplies? Either, is it necessary to multiply the duration in seconds...

Hi Let us firstly look at the source code of the pan function excerpt from my nyquist-reference plug-in) Source-code for this Function (182/358): (PAN (SOUND WHERE) (VECTOR (MULT SOUND (SUM 1 (MULT -1 WHERE))) (MULT SOUND WHERE))) Category: Sound Synthesis, as found in : Nyquist.Lsp Description: Pan...

Re: A Study in Pink
I think that our examples are quite fast for Nyquist code that verges in such a manner to DSP implementations. Most functions are very fast as long as we do not try to gather information. For example, sref is very slow because it evalueates the whole sound to get the last value. There is unfortunate...
