Re: Wahwah effect on 16-bit PCM data

A "Wahwah" effect is basically a sweeping filter. Typically it's a low-pass filter with resonance at the filter frequency. The Audacity Wahwah effect uses a low frequency sine to sweep the filter frequency up and down. It may be easier to write the effect from scratch rather than adapt the...

Re: Recording Skype

Is skype recorder a good product? I've been looking at this recently and as far as I can tell it appears to be a genuine product. I've not used it myself (I'm on Linux not Windows) so I can't personally advise on this product. There are several other Skype recording programs that are definitely bad...

Re: Selecting & Deleting very small pieces of audio

Moreover (and this goes out also to the senior forum member who previously answered my post) I swear I've done the same exact thing I'm trying to accomplish at least a couple of dozen times in the past and it worked... with the BETA version. I just can't figure out what changed and it's driving me ...

Re: First time user, can't see Canopus box in Devices

Audacity only looks for "audio devices" to capture audio data. If your computer "sees" the Canopus box as a Video capture device, then Audacity will not see it at all. If you're able to make your computer "see" the Canopus box as an "Audio device", then you sh...

Re: Selecting & Deleting very small pieces of audio

I have a couple of live (concert) mp3 music files. In the form I recieved them there's not a smooth transition from the end of one file to the beginning of the next. Upon zooming in on the end of one file or the beginning of another I notice a tiny bit of silence (flat blue line) causing this brief...

Re: It doesn't record - need help

Everything was fine as far as adjusting the levels and keeping the wave within the box which I think I’m supposed to do Yes, absolutely. If the waveform touches the top or bottom of the track it will produce distortion which is very important to avoid because it's virtually impossible to fix effect...

Re: How to make up for decibel loss in High/Lowpass filter

Interesting post kai.fisher. In the code example, why (- len 1) ? For all audio selections, (snd-t0 s) is zero (and the logical duration of the selection is always 1.0) so shouldn't time just be (/ len *sound-srate*) in (/ <integrated square> time) ? But then the final sample is "1" sample...

Re: Cascade Filter (recursive function) - Help

I am an acoustic consultant and more and more frequently have to analyse recorded wav files (recorded on our level metre). Its very handy to be able to do this in audacity directly. So I have been trying to get ISO standard compliant octave band and 1/3 octave band filters coded. 99% done now. Exce...

The default track name is "Audio Track" (left end of the track)
