- [Audio Resample Speed](https://elysiatools.com/en/tools/audio-resample-speed): Change speed by resampling (pitch shifts with speed)
- [Audio Robotize](https://elysiatools.com/en/tools/audio-robotize): Apply a robot voice effect (pitch and bit crush)
- [Audio Set Pitch](https://elysiatools.com/en/tools/audio-set-pitch): Set pitch up or down without changing speed
- [Audio Set Speed](https://elysiatools.com/en/tools/audio-set-speed): Set audio playback speed without changing pitch
- [Audio Slow Down](https://elysiatools.com/en/tools/audio-slow-down): Slow down audio playback without changing pitch
- [Audio Speed Changer](https://elysiatools.com/en/tools/audio-speed-changer): Change audio playback speed while maintaining original pitch using time-stretching algorithms
- [Audio Speed Up](https://elysiatools.com/en/tools/audio-speed-up): Speed up audio playback without changing pitch
- [Audio Tempo Change](https://elysiatools.com/en/tools/audio-tempo-change): Change audio tempo without changing pitch
- [Audio Time Stretch & Pitch](https://elysiatools.com/en/tools/audio-time-stretch-pitch): Change speed without pitch, or pitch without speed

- [Voice Gender Privacy Filter](https://elysiatools.com/en/tools/audio-voice-gender-privacy-filter): Shift pitch/formant cues and dynamics to reduce simple speaker-identification cues while preserving duration.
- [Audio Wow Flutter Corrector](https://elysiatools.com/en/tools/audio-wow-flutter-corrector): Reduce mild tape speed wobble and compensate known speed offset in audio recordings.
- [Chain Sprocket Ratio Calculator](https://elysiatools.com/en/tools/chain-sprocket-ratio): Calculate the ratio, driven speed and chain linear speed of a chain drive. i = z₂/z₁ = n₁/n₂, chain speed v = z₁·p·n₁/60000. Enter the pitch to compute chain speed.
- [Gear Module Calculator](https://elysiatools.com/en/tools/gear-module-calculator): Calculate the gear module m. m = d/z = p/π. Solve the module from the pitch diameter d and tooth count z, or from the circular pitch p. Also returns the pitch diameter, circular pitch and addendum.
