BPM Changer and Music Speed Changer

Use the music speed changer as a BPM changer

The new tempo is the original BPM multiplied by the speed. To reach a target tempo, divide the target BPM by the current BPM. The slider moves in steps of 0.05, so pick the nearest step.

Example: to take a 120 BPM track to 128 BPM, 128 ÷ 120 = 1.067, so choose 1.05× (126 BPM) or 1.10× (132 BPM). Find the current tempo with the Key & BPM Finder.

Slow down music to learn it

• Learn a fast solo or riff at 0.5× to 0.75×, then raise the speed as you get it.
• Transcribe melodies and chords at a slower tempo; the notes stay in the original key.
• Rehearse choreography or a workout routine at a gentler pace.
• Speed up a podcast, lecture or voice memo to 1.25× or 1.5× to get through it faster.

Sped-up and slowed versions

Sped-up songs on TikTok and Reels usually raise the pitch along with the tempo, which is what the Nightcore Maker does. This tool keeps the original pitch, which sounds more natural for practice and for matching tempos in a DJ set.

For the slowed sound with a deeper pitch and a reverb tail, use the Slowed and Reverb Generator, which changes speed, pitch and reverb in one render.

Sound quality at extreme speeds

• Between 0.75× and 1.25×, most music sounds natural.
• At 0.5×, drums and consonants can smear, because every sound is stretched to twice its length.
• At 2×, fast passages can sound choppy, while speech usually stays clear.
• Use a lossless source, such as WAV or FLAC, for the cleanest result.

Using songs you have the right to use

Slowing a song down to practice is personal use. A sped-up or slowed copy of someone else’s recording is still their recording, so publishing it needs permission from the rights holders.
