Wavefolder vs Chordpeek

Wavefolding is widely used in modular synthesis and experimental music production to add character, aggression, or shimmer to sound sources. Unlike simple hard clipping, which crushes transients, wavefolding preserves amplitude information by folding back on itself.

Turn guitar ideas into saved chord charts you can rehearse, back up and share. NEW IN 4.0 • Export a portable songbook backup and preview a restore before importing. Identical charts are skipped; changed copies stay separate. • Export an authored songboard as a MIDI chord track with its tempo, beat lengths and section markers. • Export a printable PDF rehearsal sheet with chord names, beat positions, sections and guitar shapes. • Keep your practice brief between launches, with safer songbook and practice-history storage. SONGBOARD STUDIO Create charts, add chord events, organize sections, set tempo and meter, transpose and follow rehearsal cues. Use the chord library or capture a suggested microphone match, then check the chart before saving. CAPO ARRANGER Find a capo position for the whole song. Compare frets 0–7 by default, with an adjustable range up to fret 9. Read sounding chords, played shapes and six-string fingerings for each event, then share the arrangement as text. The saved songboard stays unchanged. GUITAR TOOLS Explore the chord library, tuner, progressions, scales, ear training, metronome and practice tools. Live microphone processing stays on device; audio is not recorded or uploaded. WHAT TO KNOW Microphone chord matches and key suggestions are estimates. Note-match scores are not probabilities of correctness. Noise, tuning and playing style affect results. Capo arrangements use standard EADGBE tuning. Shape rankings are effort heuristics, not guarantees of comfort. Check the shapes on your instrument; unavailable shapes are disclosed. MIDI exports contain generated block chords, not recorded audio, strumming or the original guitar voicing. PDF sheets describe your authored chart rather than transcribing a recording. Songbook backups include charts, events, sections and tempo, not favorites or practice history. Backup files are limited to 8 MB and 512 charts. New-chart creation is limited to 32 charts; existing and restored larger collections are retained. Each chart supports up to 128 events. Keep exported backups in a safe location.
