Nightcore Maker & Creator.

Set a playback rate or move a track from its source BPM to an exact target BPM. Tempo and pitch rise together — the classic nightcore transform.

TIME + SPACE MAP

Nightcore Energy Ramp

Trace the dry event into motion, repeats or ambience. The visual separates the direct sound from what arrives later, making timing, density, feedback and stereo movement easier to reason about.

  1. Original track

    Start with the right material

    High-energy edits, AMV-style versions and matching a known source BPM to a faster target without hiding the pitch lift.

  2. Raise speed and pitch

    Understand the transformation

    Chunked playback-rate resampling applies the calculated rate, a measured five-millisecond edge fade prevents boundary clicks, and pitch is intentionally not preserved.

  3. Nightcore edit

    Verify the usable result

    A shorter exact-frame render with synchronized original/result A/B plus a JSON receipt for rate, BPM, semitones, cents, duration, frames and peaks.

Pitch-speed lift

Where this workflow stops

The source BPM is user-supplied rather than detected here. Bright material can become harsh, and the 100 MB source plus decoded-memory and duration guards set practical bounds.

THREE-PASS CHECK

Make the final decision by ear

  • Judge timing against the rhythm rather than in solo.
  • Check whether the tail masks the next word, note or transient.
  • Audition mono and headphones when the effect uses stereo motion.

How to use the nightcore maker

  1. Drop a song into the nightcore creator. It decodes locally; the audio is not uploaded.
  2. Use Rate for a 115%, 125% or 135% preset, or choose Target BPM and enter the source and target tempo.
  3. Check the exact rate, result BPM, pitch lift in semitones and cents, and predicted frame count before rendering.
  4. Render, switch between Original A and Nightcore B, then download MP3, WAV or the JSON render receipt.

Nightcore maker answer: classic nightcore plays audio faster, so tempo and pitch increase together. The exact pitch lift is 12 × log2(rate) semitones. Moving 120 BPM to 150 BPM uses a 1.25x rate and raises pitch by about 3.8631 semitones or 386.31 cents.

The result is shorter by the same rate. This creator writes exactly ceil(source frames ÷ rate) frames and reports that number, the output duration and the formula in its receipt. It uses a short 5 ms raised-cosine boundary fade only when a measured edge is above the click-risk threshold.

Nightcore: quick answer and technical limits

Quick answer: A classic nightcore creator with direct-rate and target-BPM modes that raise tempo and pitch together and disclose the exact coupled change.

FAQ

How do I make nightcore at an exact target BPM?
Choose Target BPM, enter the song's source BPM and your target BPM, then render. The maker uses target BPM divided by source BPM as the exact playback rate; for example, 120 to 150 BPM is 1.25x.
Does a nightcore maker raise pitch as well as tempo?
Yes. Classic nightcore is coupled playback-rate resampling, so tempo and pitch rise together. This creator does not preserve pitch. It reports the pitch lift as 12 times log base 2 of the playback rate in semitones, plus the equivalent cents.
What does the 1.25x nightcore preset do?
A 1.25x rate makes the track 25 percent faster, multiplies its BPM by 1.25 and lifts pitch by about 3.8631 semitones or 386.31 cents. The exact output length is the source frame count divided by 1.25 and rounded up to a whole frame.
Is this nightcore generator free and private?
Yes. The core audio render runs in this browser and the selected song is not uploaded to AudioWrench. The tool has no signup or watermark, caps the compressed source before decoding, serializes decode jobs, then enforces decoded-memory and duration guards once browser decoding reveals the PCM dimensions.
