    Pitch changes. Timing stays.

    Change pitch without changing speed

    Move the complete recording up or down while its rhythm, length and sync points stay in place. A −2 semitone shift lowers every note by one whole tone without slowing the performance.

    • Transpose the entire mix by a musical interval
    • Keep the original playback speed and duration by default
    • Compare the same passage before creating the full result

    The waveform and timeline stay aligned while every note moves down by the selected interval.

    From broad moves to fine tuning

    Choose the new pitch three ways

    Use the control that matches what you already know: the interval, a small tuning difference, or the source and target musical keys.

    Semitones

    Change the key in half-step intervals. ±12 semitones is one full octave; ±2 is one whole tone.

    Cents

    Fine-tune audio that sits slightly sharp or flat. One hundred cents equals one semitone.

    Source key → target key

    Review the estimated source key, correct it if needed and choose the key you want the full recording to reach.

    One shift, different outcomes

    What do you want to change?

    Choose a familiar job to see where pitch shifting belongs and which AudioMuse control to use first.

    Move a backing track into a more comfortable singing range

    Transpose the finished recording without slowing down the groove. Small whole-step changes are a practical place to start for rehearsal or a cover.

    1. 1

      Review the estimated source key or enter the key you know.

    2. 2

      Lower or raise the track by one or two semitones first.

    3. 3

      Compare the chorus, then create the full adjusted file.

    Use the tool that matches the change

    Pitch, speed, BPM and note correction describe different jobs. Keeping those jobs separate makes the result easier to predict.

    Small shifts usually sound more natural. Large changes can make exposed vocals, cymbals or complex full mixes sound less natural, so preview an important passage first.

    Pitch Changer FAQs

    Semitones, cents, song keys, video pitch, privacy and download formats.

    Can I change pitch without changing speed?

    Yes. In Audio mode, leave Keep original speed and duration enabled. Video mode always preserves speed and timing. To independently slow down or speed up an audio recording, use Audio Speed and Pitch Changer.

    How do I use the video pitch changer?

    Select Video above the upload area, upload a local video and choose a shift from −12 to +12 semitones. Select Preview Video to compare Original and Adjusted, then Export MP4. You can also export directly without creating a preview first.

    Can I change a song to a different key?

    Yes. Shift by semitones in either mode. In Audio mode, you can also review the estimated source key and choose a target key. Correct the estimate if you know the original key. Transposition moves the entire recording and preserves its major or minor character; it is not automatic vocal pitch correction.

    Which audio and video formats are supported?

    Audio mode accepts MP3, WAV, FLAC, M4A, AAC, OGG and other supported audio formats; an MP4 with audio produces audio-only output in that mode. Video mode accepts MP4, MOV, M4V, WebM and MKV and exports MP4 with picture and sound. Both modes accept one file up to 100 MB and 10 minutes. Readable codecs and sufficient device memory are required.

    Will my video keep its picture quality?

    H.264 video is copied without re-encoding the picture. Other supported codecs are converted to H.264 for MP4 output, which can change picture quality and take longer. The processed audio is stereo AAC at 192 kbps. Large pitch shifts can introduce audible artifacts.

    Can I change the pitch of a YouTube video?

    This tool accepts local files, not YouTube links. It does not download from YouTube or change playback on the YouTube website. Choose Video and upload a local file you own or have permission to edit.

    Does choosing an audio preview passage trim my download?

    No. The selected 0.1–30 second passage in Audio mode is only for comparing the sound. Your download includes the full recording. Video mode previews and exports the full video.

    What happens to multiple audio tracks and subtitles?

    Video mode processes the first audio track and includes it with the video in the MP4. Extra audio tracks and subtitles are not included. The tool shows a notice when multiple audio tracks are detected.

    Is Pitch Changer free, and do files stay private?

    Audio and video pitch adjustment, preview and download are free without sign-up. Processing runs in your browser; your media files are not uploaded for processing. The engine downloads on first use. Keep the page open while processing and download the result before leaving.
