Record marked as obsolete and not updated for a long time.
The acm file extension seems to have been primarily related to an audio format featured in several computer games, including Fallout, Baldur's Gate or American Civil War.
Probably related to now obsolete Audio Compression Manager (ACM), which was a Windows multimedia framework for management of audio codecs (compressor/de-compressors). It was replaced by DirectX and its DirectShow component.
It seems there were several versions of this format and not all programs that support ACM may support all of the formats. Especially dedicated converters for game music usually just work for a specific game.
Winamp player with ACM plugin should be able to playback these files. It is possible some works with other media players.
You can find conversion utilities on internet that allow gamers to convert ACM audio to WAV. However most of these programs are 10+ years old and the links may be dead.

eSignal uses ACM files as part of its own working data. The exact information stored in a file depends on how eSignal created it, so the file should normally be handled by the application rather than edited manually.
ACM files are associated with the Windows version of eSignal.
Install eSignal for Microsoft Windows, then open the ACM file from within the application if eSignal does not open it automatically. An ACM file may not be meaningful in other programs.
If the file contains information that eSignal can export, use the application's export features to save it in a supported format; otherwise, retain and use it with eSignal.

FreeBSD is an open-source Unix-like operating system. In this context, an ACM file is an installation-package archive associated with FreeBSD.
ACM files were found in FreeBSD installation packages.
ACM files are associated with FreeBSD installation packages. Try opening the file on FreeBSD with the package-management tools appropriate to the package that supplied it.
There is no standard conversion from an ACM file to a document or another ordinary file format. It should normally be used as the FreeBSD installation package for which it was supplied.

The acm file extension is associated with the Visual SourceSafe application package developed by Microsoft.
Microsoft Visual SourceSafe (VSS) is a source control software package oriented towards small software development projects. Like most source control systems, SourceSafe creates a virtual library of computer files. While most commonly used for source code, SourceSafe can actually handle any type of file in its database, but prior versions have been shown to be unstable when confronted with large amounts of non-textual data (images, binary executables, etc).
Use compatible tools to work with *.acm files.
Probably cannot be converted to other formats.
