The spectrum analyzers in Strawberry are a nice visual feature in the app, but there's one small thing about them that bugs me: unless I'm mistaken, they operate on a linear frequency scale. Mathematically speaking, this means that the entire right half of the spectrum analyzer is occupied by the frequency band between about 10.025 kHz and 22.05 kHz on a standard CD-quality recording.
Practically speaking, this means that said entire right half covers only what our brains interpret as extremely high treble, basically only lit up when a cymbal crashes. It also means that actual melodic lines are extremely hard to pick out, given they only occupy a tiny portion of the spectrum analyzer's width—and even in that narrow band, they are almost always completely drowned out by every percussion instrument.
I've used a logarithmic spectrogram before, and I know that they can help with this problem. If the x-axis of the spectrogram used a logarithmic frequency scale, then it would be much easier to read for melodic information. Essentially this would mean devoting equal width to the band between 100 Hz and 1 kHz as to the band between 1 kHz and 10 kHz, etc. Unless it would require significantly higher computing resources to display, I believe it would be a nice, simple improvement to what is already probably the best music player on Linux. Thank you for considering my suggestion!
