‘Tuniac’ is a simple and a memory friendly music manager for Windows. It supports a lot of audio formats (not only audio files, you can even add video files into its window and will still play the audio track!) has an ‘iTunes’ inspired user interface and loads pretty much in an ‘instant’.
It also has a ‘Preferences’ window that lets you adjust the file associations, disabling screensavers being shown up during playback, change the number of items kept in the ‘history list’, configure the media library (including Rebuilding it), enable/disable built-in plugins, and many more.
It also comes with a simple but a beautiful visualizing plugin (you can also configure it to use less or more CPU time), has a basic equalizer, supports ‘volume gaining’, displays album-arts, lets you create/edit playlists, supports playing: flac, mp3, aac/m4a/mp4/3gp, opus, ogg, ac3, alac, ape, cdda, midi, mpc, ofs/ofr, tak, tta, wv and online radio streams.
I tested its performance by adding about 801 audio files from various locations on my HDD (a music library that has 801 songs ain’t anywhere near your standards, this I know! :D). It scanned and added them to the library pretty fast, though the initial memory usage was around 5.5 MB (in Windows 8), when the library was created it went up to 8.3 MB.
This however is because when adding files, it has to create a database and probably has to load another plugin (s) etc. Anyhow, after it finished adding the files, I closed it and reopened it. And the memory usage was again reduced to its usual start-up level of 5.4-5.5 MB.
The memory usage can reach around 8 MB but it usually stays around the 5-6 MB mark. It was also extremely stable, never crashed, plus the responsiveness was really good. The audios were ‘Paused’ or ‘Resumed’ pretty much without any delays. File search was also the same, lightning fast :).
So, as an ending note, if your old computer can hardly keep up with them fancy music managers or if you just don’t like them, then I humbly recommend ‘Tuniac’. Please visit this page for downloading it.
