Frequently Asked Questions
What is BPM?
BPM means beats per minute. It defines the song tempo and is essential for beat-matching, DJ mixing, and video editing transitions.
Why does musical key matter?
Musical key tells you the tonal center of a song. DJs use key matching (harmonic mixing) to blend tracks smoothly, and producers need it for mashups, remixes, and sampling in the right pitch.
Which platforms are supported?
TikTok, YouTube Shorts, Instagram, and Twitter/X video links are supported. For YouTube, use Shorts URLs. You can also upload local audio or video files.
What file formats are supported for upload?
We support audio files (MP3, WAV, FLAC, AAC, OGG, M4A) and video files (MP4, MOV, WebM). The maximum file size is 50MB. For video files, we automatically extract the audio track before analysis.
What do the extra audio features mean?
Energy reflects intensity, Danceability indicates movement-friendliness, Valence indicates mood, and the remaining metrics describe acoustic, vocal, and live-performance characteristics.
