Audio Pitch Changer
Audio Pitch Changer shifts the pitch of an audio file up or down in semitone steps while keeping the duration as close to the original as possible. Upload an audio file, choose a pitch shift from -12 to +12 semitones (one octave down or up), and click Change pitch to download a processed MP3. This is useful for transposing a backing track to a more comfortable key, adjusting a voice recording for creative effects, or matching reference tones during practice. The backend uses FFmpeg audio filters to perform a duration-aware pitch shift by resampling and then compensating tempo so playback length stays similar while pitch moves by the selected semitones. The tool includes a Sample input button so you can hear the effect immediately, and it reports the chosen semitone shift and pitch ratio in the result. An optional AI Assistant can suggest a starting semitone value for common goals (like “deeper voice,” “chipmunk effect,” or “match instrument key”), but it only runs when you click and never changes your file automatically.

Chipmunk Voice Generator
Chipmunk Voice Generator lets you create a classic high-pitched “chipmunk” effect from any audio recording by shifting pitch up in semitones. Upload a file, choose how many semitones to raise the pitch (from subtle to extreme), and optionally decide whether to keep the original duration. When duration is preserved, the tool applies a pitch-shift chain that compensates tempo so the timing stays similar; when duration is not preserved, the pitch shift also speeds up playback for a more traditional chipmunk feel. Processing is done on the backend with FFmpeg, so you can use it on mobile or desktop without installing software. Free plans support audio uploads up to 20MB, while paid plans unlock uploads up to 50MB. Download the result as MP3 for easy sharing or as WAV for an uncompressed intermediate you can edit further. An optional AI Assistant can recommend a conservative pitch setting and whether to keep duration based on your content type and desired intensity, and it only runs when you click the button with all AI processing handled securely on the backend.

Deep Voice Generator
Deep Voice Generator helps you make any voice recording sound deeper, richer, and more commanding by lowering pitch in controlled semitone steps and optionally adding a gentle bass emphasis. Upload an audio file, pick a depth setting from -2 to -14 semitones, decide whether to keep the original duration for a more natural result, and choose an output format (MP3 or WAV). The backend processes your upload with an FFmpeg pitch-shift pipeline designed to preserve timing when Keep duration is enabled; if you disable it, the output will slow down along with the pitch change for a heavier effect. You can also add a conservative bass boost (0–12 dB) to increase low-end presence for narration, gaming personas, voiceovers, or dramatic character lines. A Sample input button provides a real audio example so you can test the workflow instantly. An optional AI Assistant can recommend safe settings (depth, duration preference, and bass boost) based on your content type and desired vibe, but it only runs when you click and all AI processing is handled securely on the backend.
