A2M converts local audio into editable MIDI using a trained piano model. No uploads, no accounts, and no cloud dependency.
A model download is required once on first launch (~165 MB).
Best results come from solo piano recordings. Mixed tracks or full songs will be less accurate.

This program makes a linux computer equipped with a modern sound card behave as a traditional hi-fi preamp, but able also to make advanced DSP equalization and crossover tasks.
That means that, with a proper soundcard, external sources can be used, be them analog or digital, along with digital libraries or streamed sources.

The AFsp package is a library of routines for reading and writing
audio files. The emphasis is on providing support for the type of
audio file used by the speech processing research community. The
routines have been designed to be easy to use, yet provide transparent
support the reading of several audio file formats. A secondary
purpose for distributing these routines is to encourage the use of a
standard audio file format for the header information in the output
files.
The following file formats are supported for reading.
The audio file open routine automatically senses the file type and
communicates it to the audio file reading routines. Formats are
converted on the fly as the file is read, so the user manipulates
floats and doesn’t need to worry about the underlying data format.
For writing, the routines produce a standard format file, though
options are available to produce headerless files if desired. This
standard format is a compatible with the Sun audio file format. There
is provision for storing extra information in the extensible part of
the header.
Several audio file utilities (for copying, comparing, and filtering
audio files) are included in the package.

shntool is a multi-purpose WAVE data processing and reporting utility. File formats are abstracted from its core, so it can process any file that contains WAVE data, compressed or not – provided there exists a format module to handle that particular file type.
shntool has native support for .wav files. If you want it to work with other lossless audio formats, you must have the appropriate helper program installed. The “Helper programs” section below contains links to helper programs for each format that shntool supports.
