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.

Echo Effect Generator
Echo Effect Generator adds a classic repeated echo to any audio file by delaying the signal and feeding part of the delayed sound back into the effect so repeats decay over time. Upload an audio file, set a delay time (35–2000 ms) to control how far apart the echoes are, adjust feedback to control how long the echoes keep repeating, and set a wet mix to control how loud the echoes are relative to the original. This is useful for voiceovers, podcast clips, dramatic narration, sound design, and creative edits where you want clear, rhythmic repeats without opening a full audio workstation. Processing runs on the backend with FFmpeg’s audio filters, so the tool works reliably on mobile and desktop without local installs. A Sample input button provides a real audio example so you can test the flow instantly, and the output panel shows the exact delay/feedback/mix settings used so you can reproduce the sound. An optional AI Assistant can suggest safe echo settings for common use cases (ambience, podcast, dramatic, metallic), but it runs only when you click and all AI processing is handled securely on the backend.
