Re: Recording: 1 Mic + PC Sound to different Tracks

There's the "Audacity to Podcast", which deals with podcasts in general and producing them with Audacity especially.

It gives a lot of tricks about hardware, software, editing, content and legal issues.

Re: Audio Books

It is perfectly fine if you want to enjoy your audio books in your car. Audacity doesn't "burn" any CDs, you'll need an extra program for this task (one is most likely preinstalled on your computer). Audacity does the recording, editing and exporting in the appropriate format. There are several tuto...

Re: Audio Books

You don't have to copy your audio books to CD when their origin is an audio tape unless you want to use them in a (portable) CD player. If you want to create Audio CD's, most CD-Rs will go. But you could end up with a lot of CDs (similar to the quantity of your tapes). Another way is to burn the tra...

Re: Converting one MP3 file to 20 individual MP3 files.

I've been hoping that the big file was a lossless format (since you've mentioned a DVD format). You've obviously written the songs yourself, so it would be nice to have the tape archived in a lossless format, where from you always start to encode into the momentarily fashionable formats. You've ment...

Re: Echo removal?

There's a technique called "deconvolution" that can remove some echoes from a room. It is the opposite of a convolution reverb. The principle is exact the same. You have to record a loud impuls (shot, balloon, sweep etc.). Instead of multiplying the spectra of Input signal and impulse response, you ...

Re: Importing text as audio/exporting audio as text

It would be nice if data could directly be sent to the clipboard from within Nyquist, i.e. an output direction that writes "files" to the clipboard instead of a file pointer allocation on the hard drive (Feature Request?) Do you want to request that in a new post in Nyquist wish list http://forum.a...

Re: Importing text as audio/exporting audio as text

I usually copy the values from the debug window and insert them in Excel. If I want to create more than one column, I insert a special separater (% / ' etc.) and call afterwards "text in columns". This works of course only for a few hundred samples. It would be nice if data could directly be sent to...

Re: (vector (aref s 0)(aref s 0)) bug

Anything is valid that forces a new evaluation of the sound, such as (mult 1 (aref s 0)) or a similar dummy function. However, since Audacity duplicates mono sounds, nothing more is needed than '(aref s 0)'. A pity that the reverse isn't true i.e. that mono tracks are not extended to stereo tracks w...

Re: (vector (aref s 0)(aref s 0)) bug

It is enough to write (osc 60) Audacity simply copies a from Nyquist returned mono sound to both channels if a stereo track is present. That's why '(aref s 1)' copies the right one into both channels. However, normally this should be done by the code from the topic title - which produces the strange...

Re: Importing text as audio/exporting audio as text

Sounds very interesting. It would be nice if we could come up with a definite project. For example, we could export FFT frames such that they could displayed in Excel as a 3D surface diagram (a speech finger print). It hasn't to be Excel of course, there are a lot of open source programs that could ...
