Transpose Review — Pitch and Speed Control for Music Playing in the Browser

Transpose adds pitch shifting and speed control specifically designed for music — you can slow down a song for learning, raise or lower the pitch independently from speed, and loop specific sections. Where Video Speed Controller handles general video speed, Transpose targets musicians who use YouTube and other platforms for ear training, learning songs, and practice. It works on any HTML5 audio and video.

Key Features

Pitch can be shifted independently from speed — slow a song down to 50% without lowering the pitch, or raise the key by a semitone without changing the tempo. This is the critical feature for musicians that general speed controllers don't provide.

Speed adjustment works in fine increments tuned for music practice — from very slow (for note-by-note learning) to slightly faster (for technical practice runs). The increments are calibrated for musical use rather than general video consumption.

Loop controls let you set a specific section of a song to repeat — ideal for practising a specific bar, learning a chorus, or isolating a riff. The loop points can be set by clicking on the waveform visualisation.

Transpose works on YouTube, SoundCloud, Bandcamp, and most HTML5 audio and video sources — anywhere you play music through Chrome.

Who Is It For

Creators who are musicians — whether music creators, musicians who make tutorials, or creators who use music in their content and want to analyse or learn from reference tracks. The pitch shifting capability is the specific feature that separates Transpose from all general video speed tools.

Creators who are not musicians and don't use music in a technical capacity will find little use for pitch shifting. For general video speed control without pitch isolation, Video Speed Controller is more appropriate.

Pros and Cons

• ✅ Independent pitch and speed control is not available in general video speed tools
• ✅ Loop controls make specific section practice immediate
• ✅ Works across all HTML5 audio sources, not YouTube only
• ❌ Free tier has some feature limitations — full pitch range and loop features may require paid plan
• ❌ Niche use case — primarily valuable for musicians

Pricing

The free plan covers basic pitch and speed adjustment. The Pro plan ($4.99/month or one-time purchase) unlocks the full pitch range and extended loop functionality.
