What is it?
AudioTag.info — is a free music-recognition service. It allows you to identify almost any unknown piece of music quickly and easily. Its use is very simple: you upload a short audio fragment (even 15 seconds are enough) or an entire song, the robot analyzes it and provides you with the information about the track title, artist name, album title, etc. Your audio fragment can be in almost any file format and of almost any quality (aurally recognizable, of course) — it can be an MP3 file downloaded from the Internet or a short recording made with your old tape recorder and stored as a low-quality .WAV-file.
Is it free?
Yes, the service is absolutely free.
How does it work?
This service is based on a sophisticated audio recognition algorithm combining advanced audio fingerprinting technology and a large songs' database. When you upload an audio file, it is being analyzed by an audio engine. During the analysis its audio “fingerprint” is extracted and identified by comparing it to the music database. At the completion of this recognition process, information about songs with their matching probabilities are displayed on screen.
What are the supported file formats?
You can upload your files in almost any file format and with any bit-rate. Uncompressed, ADPCM and other waves (.WAV), MPEG-1 Layer III (.MP3), Ogg Vorbis (.OGG), FLAC, Flash Video (.FLV), .AMR, .MP4, and many more file formats are supported.
Is the recognition reliable?
Yes, the recognition is reliable. Of course, erroneous recognition is possible, but its probability is low. The algorithm is designed so that it will rather not identify a song than show an incorrect result.
What is an optimal duration of uploaded audio fragments?
An optimal duration of an analyzed (uploaded) piece of an audio is 15-45 seconds. Shorter and longer audio files can be recognized as well. Generally, recognition process is performed as follows: uploaded file is sliced into portions of 15 seconds each; 1 to 3 music slices are chosen at random and analyzed one by one. Therefore, to save your time and bandwidth, it is recommended to upload relatively short audio fragments of 15 to 45 seconds.
The recognition process consists of three simple steps:
1. Upload file or specify direct URL to audio file
2. Prove you are a human by answering a simple calculation task.
3. Get result.
