What's the BPM of This Song?

What this tool does

Finding the BPM of a song is as simple as uploading a clip: the AI detects the tempo and returns the primary BPM estimate with a confidence level, so you know whether the reading is solid or whether the track sits in ambiguous territory (a common issue with half-time feels that read as either 70 or 140). Alongside the number you get the time signature (4/4, 3/4, 6/8), any tempo changes including ritardando or accelerando sections, and a description of the rhythmic feel: straight, swung, shuffle, half-time, or double-time. It finishes with DJ-friendly notes on whether the track would mix well at the detected tempo. That last part matters because raw BPM alone does not tell you mixability; a 174 BPM drum and bass track and a 87 BPM hip-hop track share math but not energy. Use it for DJ set prep, remix and sampling work, music production, or settling the classic argument about whether a song is fast or just busy.

How it works

Upload any song clip and the AI analyzes the rhythmic content. Tempo detection produces the primary BPM estimate with an explicit confidence level, making educated calls on tricky material instead of refusing. Time signature analysis determines whether the track is in 4/4, 3/4, 6/8, or something less common. Tempo change detection scans for sections that slow down or speed up, including gradual ritardando and accelerando rather than just hard tempo jumps. Feel classification describes how the rhythm actually sits: straight eighths, swing, shuffle, half-time, or double-time, which is the difference between two tracks at the same BPM feeling completely different. The DJ notes then translate all of this into practical mixing guidance, like whether the tempo is stable enough to beatmatch and what tempo range it pairs with.

Benefits

• Get the BPM of any song in seconds without tapping along on a keyboard
• See a confidence level so you know when a half-time feel might read as double the tempo
• Learn the time signature, which tap-tempo tools and most BPM databases skip entirely
• Catch tempo changes and rubato sections before they wreck a DJ transition
• Understand the rhythmic feel (straight, swung, shuffle, half-time) behind the raw number
• Get DJ mixing notes on whether the track holds tempo well enough to beatmatch
• Verify the BPM of unreleased or obscure tracks that are not in any database

Tips for Best Results

• Upload a section with clear drums, since intros and ambient breakdowns give weaker tempo evidence
• If the result looks doubled or halved, check the rhythmic feel notes, because half-time and double-time feels cause exactly that
• Use a clip of at least 20 to 30 seconds so tempo changes have room to show up
• For live recordings, expect tempo drift and read the tempo change section closely
• Cross-check the time signature when a track feels off, since 6/8 often gets miscounted as 4/4
• Mention in the notes if you need the BPM for DJing, since the mixing guidance becomes more specific
• Run both the original and a remix to see how the feel changed even when the BPM did not

Popular Use Cases

• DJs finding the BPM of new tracks to slot them into a set
• Producers matching a sample or remix to the original tempo
• Musicians setting a metronome or click track to learn a song
• Dancers and choreographers picking music at a specific tempo
• Fitness instructors building playlists in target BPM ranges
• Music students analyzing tempo and meter for theory assignments
• Editors syncing video cuts to the beat of a soundtrack
• Anyone settling whether a song is actually fast or just rhythmically busy
