functions, such as symmetrically windowed sinusoids, chirps, exponentially
decaying sinusoids and whatever. The point is to have a sparse

There are chirp(let) transforms that represent
What are the alternatives to the FFT? Have wavelets been
used for real world solutions?
Sure, wavelets get used. Maybe more in image/video than audio, but I'm
certain someone can come up with some examples of wavelet audio
applications.
If an app needs much higher time resolution
and there are
We use wavelets in a pitch-tracking application some years ago
(John ffitch and Wafaa Shabana, A Wavelet-based Pitch Detector for
Musical Signals; Proceedings of DAFx99, 101--104). We did try some
other wavelet attempts with nothing useful.

Gabor transform or Wigner Distribution analysis
or their combination may be used.

There is Antoine Schmitt's Wavelet-based method, implementation available under
an MIT license:

It is optimized for voice, but I have found it generally works well with PNP
sounds.
