AIMP is a desktop audio player built around playlists, a Music Library, and separate utilities for converting and tagging files. It can play tracks stored on the computer, a network share, a supported cloud service, a podcast feed, or an Internet radio stream. AIMP differs from opening songs in a basic system player because it can keep several playlists ready, apply per-playlist views, process sound before output, and edit the metadata used to organize the collection. The player does not copy every track into its own storage, so file paths still matter.
Playlists stay separate
Several playlists can remain open while only one supplies the current playback queue. AIMP can show one playlist as single-line entries and another with grouped fields or a different layout. Searching covers all open playlists, while locking a playlist prevents accidental content changes.
A playlist normally points to the original file. Moving or renaming that file in Explorer can leave an entry that AIMP cannot resolve. A smart playlist based on Music Library fields has a different dependency: changing a genre, rating, or watched folder can change its membership without manually editing the list. Backing up a playlist alone does not back up the audio it references.
Choose an output
AIMP can send audio through DirectSound, ASIO, WASAPI, or WASAPI Exclusive when the device and driver support them. Shared output works beside browsers and meeting clients. Exclusive output gives AIMP direct use of the selected device and can preserve a requested format without the ordinary shared mixer.
Exclusive use can also silence another application that needs the same speakers or converter. A sample rate that the device rejects may stop playback until the output format changes. Selecting ASIO requires a working ASIO driver; choosing the label alone does not create one. The Audio Path and device settings need to match the actual hardware rather than a generic recommendation.
Library and loudness
The Music Library indexes tracks and stores playback statistics, ratings, and fields used by smart playlists. AIMP can read album art from tags, the containing folder, or an online lookup. ReplayGain analysis writes loudness information that the player can use to reduce large volume differences between tracks or albums.
ReplayGain does not repair clipping inside an already damaged recording. Track gain and album gain also answer different questions: track mode evens out separate songs, while album mode preserves the relative loudness within one release. Applying the wrong mode can make a quiet interlude jump toward the loud songs around it.
Convert with intent
The Audio Converter can write one result for each source, combine a folder into one result, or merge all selected sources. The combined modes can create a CUE sheet so one long file retains track boundaries. AIMP can also read an audio CD and use multiple threads during encoding.
Conversion cannot restore detail that a lossy source discarded. Turning a low-bitrate file into FLAC makes a larger file with the same underlying loss. Encoder availability also depends on the installed converter components. If an expected output format is missing, the related encoder plug-in may be absent rather than the input file being unreadable.
Batch tag work
The Tag Editor handles individual files or a selected group. It can fill fields from a filename, calculate track numbers, change letter case, fetch album information, calculate ReplayGain, and rename or sort files with a template. It also edits chapters and CUE markup for long recordings.
Batch renaming changes paths for every matched file, which can break playlists used by another player or device. Auto-filled fields can also repeat a mistake across an entire album when the filename pattern does not match every track. Reviewing the proposed names and testing a small selection keeps a template error from reorganizing the whole library.
Radio recording
AIMP opens Internet radio stream addresses and compatible playlist links. It can record a stream into supported formats or capture certain MP3 and AAC streams without re-encoding. The station controls what metadata and audio boundaries arrive. A stream that carries no reliable title changes may produce one long recording, and a station can restrict recording regardless of the visible control.
