Complete tool overview

1. Vocal Remover
Remove vocals from any song to create instrumentals, karaoke tracks, or acapellas. The core tool for isolation and extraction. Use for backing tracks, practice stems, and remixing foundations.
2. Stem Splitter
Split songs into 4 stems: vocals, drums, bass, and melody. For granular remixing and layered music production. More advanced than vocal remover, ideal for deep edits and mashups.
3. Pitch Changer
Transpose audio up or down by semitones without affecting speed. Transpose instrumentals to singable keys, harmonize vocals, or key-match tracks for DJ sets.
4. BPM Finder
Instantly detect the tempo (BPM) of any song. Essential for DJs, producers, and anyone syncing tracks to beat grids or time-matching instrumentals.
5. Key Finder
Analyze the musical key, scale, and harmonic content of any track. Helps with harmonic mixing, chord progression analysis, and songwriting.
6. Audio Cutter
Trim, cut, merge, and edit audio files. Split songs into sections, remove unwanted parts, or combine clips. Basic audio editing without a DAW.
7. AI Mastering
Apply professional loudness, EQ, and compression to finalize mixes. Prepare tracks for streaming, radio, or release. One-click mastering for quick polish.
8. Noise Reducer
Remove background hiss, hum, and ambient noise from vocals, instrumentals, and recordings. Refine quality of extracted stems and live recordings.
9. Echo Remover
Reduce or eliminate reverb, echo, and delay from vocals and instruments. Useful for tightening up extracted acapellas and recordings with excessive room reflections.
10. Vocal Doubler
Layer vocals with automatic pitch-shifted copies to create fullness and width. Thicken thin vocals or create harmony effects without additional recordings.
11. Tempo Changer
Speed up or slow down audio without changing pitch. Essential for matching tempo across tracks, creating practice versions at slower speeds, or remixing.
12. Reverb Simulator
Add realistic room, hall, plate, or spring reverb to vocals and instruments. Create spacious mixes or simulate recording spaces.
13. AI Equalizer
Apply intelligent EQ to tone-shape vocals, instruments, and full mixes. Boost lows, carve mids, brighten highs, or apply genre-specific presets.
14. Dynamic Compressor
Control dynamic range with professional compression. Tame loud peaks, glue mix elements, or add punch to drums and vocals.
15. Frequency Analyzer
Visualize the frequency spectrum of any audio file. Understand where energy lives in a track, identify problematic resonances, and plan EQ moves.
