Re: Frequency change detection

That's with the file "forum femoral.wav"
The file "forum acetabular.wav" is more difficult to analyse because the way that he is hitting it changes half way through.

Re: Regular Interval Labels enhancements

I think I've covered all possible user input. Unusual, but valid user input is allowed (such as starting numbering from a negative number). Labels before zero are prevented by shifting the start time to zero. Any other invalid input will produce an error message (I hope). Please let me know if you c...

Re: Bit and Sampling rates - Real or Imagined?

The 16-bit limitation is in PortAudio, a third party library that Audacity uses to communicate with the computer sound system. As far as I'm aware this limitation still exists when using Windows drivers. However it is worth noting that the dynamic range of 16 bit audio is 96 dB which is likely to be...

Re: only records in mono

I"ll try downloading 1.3, but I really have my doubts that that is the solution. I also doubt that it is the solution, but it will make trouble shooting the problem a lot easier as Audacity 1.3 can be configured in a more rational way than 1.2. It will also save a lot of confusion as it's also...

Re: Frequency change detection

To be honest, the idea of sawing off the top of the femur, reaming it out and driving in a metal spike make me feel a little queasy, but how the ear is able to pick out the subtle change in sound is fascinating. The same phenomena is encountered in many other situations where a metal spike is being ...

Re: recording synth audio to the mic input

Most probably yes. A line level signal is around 1000 x greater than a microphone signal.
Assuming that there is an output level control on the Nord Lead, even an inexpensive external sound card such as the Behringer UCA 202 should give good results.

Re: Regular Interval Labels enhancements

If you choose a negative number to start, it will work fine. If you put a letter in instead of a number it just starts at zero! Yes I've got that one covered, but (silly example) try typing "hello" into the "Label interval [seconds]" box, then click the "Debug" button....

Re: Keeping existing plug-ins during install of 1.3.13

Move them out of the way, or rename the existing plug-in folder before you update Audacity.
I usually just rename the folder as "plug-ins-old", then copy plug-ins over from "plug-ins-old" to the new "plug-ins" folder after updating.

Re: update oggvorbis dll

anyway it seems if I want to update the vorbis dll I guess I have to recompile the package. Audacity does not use the ogg vorbis dll. The ogg vorbis library is built into Audacity, not as a separate dll. anyway it seems if I want to update the vorbis dll I guess I have to recompile the package. Or ...

Re: Regular Interval Labels enhancements

I've noticed that there is no error message for invalid time intervals or invalid number of labels.
I'll need to tidy up the error checking in the next version (but that won't be tonight ;) )
