- The guitar, bass, saxophone, strings, harp, flute and brass samples were collected and edited (trimmed, volume-matched, cleaned up and tuned) by Nicholaus Brosowsky for tonejs-instruments. Its samples are released under CC BY 3.0.
- The Erhu is shaped in the app from the VSCO violin, and the Mandolin from the FluidR3 steel-string guitar. The Electric Guitar recording goes through an amp stage in the app, and the Acoustic Guitar (Real) plays the nylon-string guitar voiced brighter. The Violin, Cello and Strings notes are 3 seconds long in the soundfont, so the app loops their steady part when it loads them and a note can be held as long as you like. The top octave of the Violin, Erhu, Strings and Flute plays quieter so it doesn't pierce.
- The sets marked "hosted with the app" were converted (split into notes, tuned and levelled as described above) and are served with Fledgetone; the others load straight from the projects above, unchanged.
Sound effect recordings
The recordings the sound effects maker layers under its modern sounds are all public domain (CC0), trimmed, levelled and converted to MP3, and served with Fledgetone (fledgetone-sfx/README.txt lists which is which). With thanks to the people who made them:
