Audacity Forum

I want to compare the levels at the same frequencies of different audio samples. 'Plot spectrum' chooses different frequencies to report levels. How do I specify which? say, every 20 Hz from 20 to 5,000

I want to identify which person is speaking. People have worked on this; technology for it exists. A frequency spectrum from a Fourier transform would be a good start. Audacity gets some of this information. Perhaps an Audacity user has tried it.

I have audio I wish to identify the speakers in. I know they're in a subset of about 10 possible speakers, have known samples of their speech. Is there a way to compare unknown samples to known samples to identify the speaker?

Slackware, kernel 5.10.1, Audacity 2.4.2, I compiled it myself today.

I had a working version of wxWidgets. It seemed to be the current version the first place I looked. I downloaded the source anew but still couldn't build. More searching turned up version 3.04 which I could build, then I could build Audacity. Apologize for my bungling.

I switched to 64-bit (Slackware 14.2, updated daily, kernel 4.17.1, self-built). I downloaded the latest Audacity (2.2.2-rc1) When I build I get: In file included from gtk/FileDialogPrivate.cpp:23:0: /usr/local/include/wx-3.0/wx/filename.h: In static member function 'static wxUniChar wxFileName::Get...

The speakers were speaking in a quiet studio. I expect to identify only solo voices. I find a couple of open-source projects on-line, but they are very old. There are a few commercial products.

I want to identify the speakers in some recorded conversations. It's a small group, about 10. I have large samples of their speech, so I could create reliable voiceprints for each.

Has anyone ideas for how to think about this?

Thanks. I uploaded a different sample than I analyzed. I had already
converted the sample I described to mp3 and deleted the .wav. I see
this one as having peaks at 35, 73, 110, 146... consistent with a
fundamental of 36.5. Curiously the 2nd-highest peak is 1904, the 52nd
harmonic.

I have a 4-cylinder engine with 1 ignition coil that fires every half-rotation. I asked in this forum so that I wouldn't have to count by inspection. I read the FAQs first; I always do. I eventually figured it out by excerpting a single second and raising 'Size' in 'Spectrum Analysis' to 4096. This ...

I want to measure the speed of my pickup truck's engine. I made an inductive pickup that I wrapped around the ignition coil's wire and recorded a few minutes of it idling. That gives me a spike twice every time my engine rotates. I had hoped to get Audacity to count the spikes for me, but I can't fi...
