Instructions

Software Instructions

Select audio files: Click “Click to select audio, or drag files here” and choose the audio files whose pitch you want to adjust. Common formats such as MP3, WAV, FLAC, M4A, AAC, OGG, OPUS, and WebM are supported. You can also load sample audio to test the process.
Set pitch parameters:
- Semitone adjustment: Raise or lower the pitch by semitones. -12 means lowering by one octave, and +12 means raising by one octave.
- Cent fine-tuning: Used for precise calibration. 100 cents equals 1 semitone, suitable for pitch conversion scenarios such as 440Hz and 432Hz.
- Common presets: Directly select presets such as up a semitone, down a semitone, up a fifth, down a fifth, up/down an octave, and 440Hz to 432Hz.
Select processing method:
- Keep playback speed unchanged: Changes only the pitch without changing the audio duration or rhythm, suitable for accompaniment tuning, singing practice, and instrument practice.
- Processing accuracy: Choose balanced processing, high-precision processing, or fast processing based on your audio quality and speed needs.
- Continue processing when errors occur: During batch processing, abnormal files will be skipped and the remaining audio files will continue to be processed.
Configure output parameters: Choose the output format, bitrate, sample rate, channels, output volume, and ZIP file name. Select MP3 for playback compatibility, or WAV or FLAC when you need to preserve more detail.
Save settings: Click “Save settings” to record the current parameters, which will be applied automatically the next time you open the tool.
Start processing: After entering the “Process & Download” page, click “Start Adjusting Pitch,” and the tool will process all selected files according to your settings.
Preview and download: After processing is complete, you can preview the first 20 results. Individual files can be downloaded separately, and all results can be saved at once via “Download All Results as ZIP.”

FAQ

A: A semitone is a commonly used pitch unit in music, and 12 semitones equal 1 octave; a cent is used for finer adjustments, and 100 cents equal 1 semitone. Semitones are commonly used for everyday pitch shifting, while cents can be used for pitch calibration.

A: This is suitable for scenarios such as changing the key of karaoke accompaniments, helping singers find a suitable vocal range, practicing along with instruments, and matching recording keys. When enabled, it will try to keep the original audio duration and rhythm while only adjusting the pitch.

A: 440Hz and 432Hz are common reference frequencies for the note A. Converting 440Hz to 432Hz requires lowering the audio by about 32 cents, and the preset in the tool will automatically enter the corresponding fine-tuning value.

A: Slight pitch increases or decreases usually have minimal impact. The larger the adjustment, the more likely the sound texture may change. It is recommended to preview with balanced processing first. If you require high detail, choose high-precision processing and export as WAV or FLAC.

A: Result files use the original file names by default, with only the selected output format replaced. If duplicate file names occur, the system will automatically add a number to the file name to prevent results from overwriting each other.

A: Export to MP3, WAV, FLAC, M4A, AAC, OGG, WebM, and other formats is supported. MP3 is suitable for general playback, WAV is suitable for post-production editing, and FLAC is suitable for preserving more audio detail.

A: Common causes include file corruption, non-standard formatting, overly large files, insufficient device memory, or parameter combinations that are not suitable for the current audio. You can try switching to WAV output, processing files in batches, or first converting the source file to a common audio format.
