# dlt2000/xc-soundfont-synth

> An ESP-IDF component that turns SoundFont (SF2) files into PCM16 stereo audio for DIY electronic instruments, using TinySoundFont under the hood. It handles note events, expression and legato, and passes rendered audio to your own output backend.

- Magnitude: 3.8 out of 10 — Early signal

## Useful for

- Build an electronic wind instrument firmware that maps breath sensor input to note pitch and loudness.
- Render SoundFont notes to I2S from an ESP32 board with a filesystem-mounted SF2 file.
- Add light reverb and ~5 ms legato transitions between notes in a monophonic sensor-driven instrument.

## Why it’s here

- Star-counter measurements on 2026-10-26 (UTC), 18:33–21:45: 156 → 172 stars (+16). This is the change over that interval.
- Estimated end-of-day forecast: about +18 stars, using observed gains and the previous day.
- The repository is 2 days old and already has 172 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.
- Top new repositories this week: #138.
- About 5 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 11
- Issues and pull requests: 0
- Watchers: 0
- Average over the last week: 39 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 1

## Stars per day, last 3 days (oldest → newest, today is partial)

2026-10-24 … 2026-10-26: 57, 42, 16

## Spotted in now

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
