By mousing over the spectrogram, you'll be able to see your F3 as the second to last number on the bar at the bottom. For me, the blue line is the third formant, which for males falls between ~2,250hz and ~2,900hz depending on the vowel, while female F3 on the other hand falls anywhere from ~2,600hz to ~3450hz. For me, the software defaulted to showing four formants. PHONEDIT Signaix is free of charge and can be downloaded. The spectrogram plot above the pitch contour at the bottom, (the thing with the red, green, blue, and yellow), shows you a number of formants. ANVIL is written in Java and runs on Windows, Macintosh and Unix platforms. You can use Wavesurfer for resonance analysis as well. Simply by moving your mouse over the section of the screen with the y-axis labeled "hz" (the one with the disconnected tiny squares), you can see your pitch at any moment during the recording in the bottom left. Once you press stop, after a half-second or so, wavesurfer will finish processing your audio. During the recording, you will see some artifacting/noise which represents ambient sound, but we can clean that up by stopping the recording. You can increase the resolution by dragging that part of the window larger. Step 4: Click the record button, and watch your pitch in realtime represented by the little boxes moving across the screen at the bottom. Click on Create a pane and then in the menu that pops up click "pitch contour". When you hit the right section of the screen, you'll see a popup which looks like the image. Step 3: Then, and this is the tricky part: Right click on the bit of grey beneath the recording bar. Step 2: In the window that pops up, navigate to the "Sound/IO" tab on the far right, and make sure that "New sound default channels:" is set to 1. It's okay if your screen looks a bit different than mine, I've already set things up. Step 1: Today, we're going to learn how to use Wavesurfer to analyse your voice frequency. I doubt Wavesurfer will be moved and hosted elsewhere, but if you're reading this in a few years and for some reason the link doesn't work, just google around a bit and I'm sure you'll find its new home.Īnyway, here's the tutorial ( You can also view it all as a self-contained imgur album): Note, at the time of writing, it's being hosted on Sourceforge, a hosting website which has been getting a lot of bad press over the past few weeks, and a lot of software developers have moved their code from Sourceforge elsewhere. You can download Wavesurfer for GNU/Linux, Windows, and OS X here. Wavesurfer lets you do pitch analysis in real time as well as analysing it once stopped, and it allows for analysing on a much finer level. Less known, at least in trans circles, Wavesurfer is another tool for audio analysis that I think is much better suited for pitch analysis. Praat's UI is pretty archaic, and I think it's also not the best tool out there.
