Lower the pitch
Pitch (Hz) 440.0 Hz
Drag the slider below 440 Hz to lower the pitch — the lower the frequency, the deeper the sound. 432 Hz gives a subtly warmer feel; 415.3 Hz is a full semitone down. For bigger drops, open the file in the Audio Studio and go down by semitones.

Frequently Asked Questions

Everything you need to know about lowering the pitch of a song or audio file.

What is a lower pitch changer?

A lower pitch changer is an online tool that makes a song or audio file sound deeper by shifting its pitch down — without changing the speed or tempo. Instead of semitone steps, this page uses a frequency slider in Hz: drag it below the 440 Hz standard and every note in the track moves down smoothly, as far as 415.3 Hz (one full semitone lower).

How do I lower the pitch of a song online?

Upload your MP3, WAV, M4A or MP4 file to KeyPitch, drag the Pitch (Hz) slider below 440 — for example to 435, 432 or all the way down to 415.3 Hz — preview the deeper result, then click Download. Your lower-pitch file opens directly in the KeyPitch Audio Studio where you can fine-tune and export.

What is the difference between lowering the pitch and slowing down a song?

Slowing down a record drops the pitch and the tempo together — the song gets deeper but also drags. A lower pitch changer separates the two: KeyPitch shifts the pitch down while the tempo stays exactly the same. If you want the classic slowed-down sound instead, try the KeyPitch Slowed + Reverb tool.

What happens when I drag the Hz slider below 440?

440 Hz is the standard tuning reference for the note A4 — the value where your track is unchanged. Every step below it lowers the pitch of the whole song: at 432 Hz the track sounds slightly warmer and darker, and at 415.3 Hz it is exactly one semitone lower than the original. The melody, chords and tempo stay identical — only the pitch drops.

Why do people lower music to 432 Hz?

432 Hz is the most popular lower tuning: many listeners describe it as softer, warmer and more relaxing than the standard 440 Hz. It is widely used for meditation tracks, sleep playlists and ambient listening. With this slider, converting any song from 440 Hz to 432 Hz takes one drag — preview the difference and keep what your ears prefer.

How much can I lower the pitch?

The Hz slider on this page covers one full semitone down — from 440 Hz to 415.3 Hz — which is ideal for fine, natural-sounding adjustments. Need a bigger drop? Click Download: your file opens in the KeyPitch Audio Studio, where the Semitones control goes down to −12 (a full octave below the original).

Can I lower the pitch without changing the tempo?

Yes. KeyPitch uses time-stretching algorithms (SoundTouch) to lower the pitch while keeping the original tempo and length. The song plays at exactly the same speed — only the pitch moves down.

Can I lower the pitch to make a voice sound deeper?

Yes — pitch lowering works on any audio: music, vocals, podcasts, voiceovers and sound effects. A small drop makes a voice sound deeper, calmer and more authoritative, which is popular for narration and content creation. Start subtle (a few Hz), because large drops quickly sound processed.

Can lowering the pitch help me sing a song that is too high?

Yes. If a track sits just above your comfortable range, lowering the pitch by a fraction of a semitone — say 440 to 430 Hz — can be enough to relax your voice. If you need a deeper change, the Audio Studio lets you drop the song by whole semitones; most singers settle between −1 and −4.

Can I lower the pitch of a karaoke or backing track?

Yes — upload the karaoke or backing track, drag the Hz slider down until it sits comfortably for your voice, preview to confirm, then download. The instrumental keeps its exact tempo, so you can perform along with it without any timing surprises.

Is lowering the pitch the same as the slowed + reverb effect?

They are related but not identical. The slowed + reverb aesthetic combines a lower pitch with a slower tempo and added reverb. This page lowers only the pitch and keeps the speed untouched. If you want the full effect in one click, use the KeyPitch Slowed + Reverb tool, which applies all three at once.

Can I lower the pitch of a YouTube video in real time?

Yes — install the KeyPitch Chrome Extension. It adds a pitch and speed panel directly on YouTube so you can lower the pitch of any video in real time, with no download. Perfect for practising along with official videos, karaoke channels and backing tracks.

Does lowering the pitch reduce audio quality?

Small drops — anywhere within this slider's one-semitone range — are virtually transparent. Larger drops applied in the Audio Studio can introduce mild artefacts. KeyPitch uses high-quality time-domain processing (SoundTouch) to keep the sound clean — for the best result, start from a WAV or high-bitrate source file.

What audio formats are supported?

KeyPitch accepts MP3, WAV, M4A and MP4 files up to 50 MB and 10 minutes long. Once in the Audio Studio, you can export your lower-pitch track as MP3 or WAV.

Is the KeyPitch lower pitch changer free?

Yes. You can upload, lower the pitch and preview any song for free. The full Audio Studio adds extra controls — semitone shifting down to −12, speed change, reverb, bass boost, 8D audio and more.

How do Hz relate to semitones when lowering pitch?

The relationship is logarithmic: frequency = 440 × 2^(semitones/12). Going down, one semitone below A4 = 440 Hz lands at about 415.3 Hz — exactly where this slider ends. So a drop to 432 Hz is roughly a third of a semitone, a subtle shift, while 415.3 Hz is a precise one-semitone drop. For −2 semitones and beyond, switch to the Semitones control in the Audio Studio.
