-# Buzz
-
-High-level audio library for Bun using ALSA with streaming support and voice activity detection.
-
-## Features
-
-- Play audio files with repeat option
-- Generate and play multi-frequency tones (dial tones, DTMF, etc.)
-- Stream audio playback with buffer tracking
-- Record audio to stream or file (WAV)
-- Volume control via ALSA mixer
-- Device discovery and selection
-- Voice activity detection via RMS calculation
-- Type-safe TypeScript API with namespace types
-- Zero external dependencies (uses ALSA `aplay` and `arecord`)
-
-## Requirements
-
-- Bun 1.0+
-- ALSA utilities (`aplay`, `arecord`, `amixer`)
-- Linux system with ALSA support
-- TypeScript 5.2+
-
-## Quick Start
-
-```typescript
-import Buzz from "./buzz"
-
-// Play an audio file
-const player = await Buzz.player()
-const playback = await player.play("./sounds/greeting.wav")
-await playback.finished()
-
-// Generate a dial tone
-const dialTone = await player.playTone([350, 440], Infinity) // infinite duration
-await Buzz.sleep(3000)
-await dialTone.stop()
-
-// Record audio
-const recorder = await Buzz.recorder()
-const recording = recorder.start()
-
-for await (const chunk of recording.stream()) {
-  const rms = Buzz.calculateRMS(chunk)
-  if (rms > 5000) {
-    console.log("Speech detected!")
-  }
-}
-```
-
-## API
-
-### Buzz Module
-
-#### `Buzz.player(label?, format?)`
-
-Create a player. Omit `label` to use the default playback device.
-
-```typescript
-const player = await Buzz.player()                           // default device
-const player = await Buzz.player(undefined, { sampleRate: 16000 }) // default device with custom format
-const player = await Buzz.player("USB Audio")                // specific device
-const player = await Buzz.player("Speaker", { sampleRate: 44100 }) // specific device with format
-```
-
-#### `Buzz.recorder(label?, format?)`
-
-Create a recorder. Omit `label` to use the default capture device.
-
-```typescript
-const recorder = await Buzz.recorder()                       // default device
-const recorder = await Buzz.recorder(undefined, { sampleRate: 16000 }) // default device with custom format
-const recorder = await Buzz.recorder("USB Microphone")       // specific device
-```
-
-#### `Buzz.setVolume(volume, label?)`
-
-Set playback volume (0.0 to 1.0).
-
-```typescript
-await Buzz.setVolume(0.5)           // 50% on default device
-await Buzz.setVolume(0.8, "Speaker") // 80% on specific device
-```
-
-#### `Buzz.getVolume(label?)`
-
-Get current playback volume.
-
-```typescript
-const volume = await Buzz.getVolume() // returns 0.0 to 1.0
-```
-
-#### `Buzz.listDevices()`
-
-List all available audio devices.
-
-```typescript
-const devices = await Buzz.listDevices()
-// [
-//   { id: 'plughw:0,0', card: 0, device: 0, label: 'bcm2835 Headphones', type: 'playback' },
-//   { id: 'plughw:1,0', card: 1, device: 0, label: 'USB Audio', type: 'capture' }
-// ]
-```
-
-#### `Buzz.calculateRMS(audioChunk)`
-
-Calculate root mean square (RMS) for voice activity detection.
-
-```typescript
-const chunk: Uint8Array = // ... audio data
-const rms = Buzz.calculateRMS(chunk)
-if (rms > 5000) {
-  console.log("Voice detected!")
-}
-```
-
-### Player
-
-#### `player.play(filePath, options?)`
-
-Play an audio file (WAV format).
-
-```typescript
-const playback = await player.play("./sounds/beep.wav")
-const playback = await player.play("./music.wav", { repeat: true })
-
-// Wait for playback to finish
-await playback.finished()
-
-// Stop playback
-await playback.stop()
-```
-
-Returns: `Buzz.Playback`
-
-Options:
-- `repeat?: boolean` - Loop the file indefinitely (default: false)
-
-#### `player.playTone(frequencies, duration)`
-
-Generate and play a tone with one or more frequencies.
-
-```typescript
-// Dial tone (350 Hz + 440 Hz)
-const dialTone = await player.playTone([350, 440], Infinity)
-
-// DTMF "1" key (697 Hz + 1209 Hz) for 200ms
-const dtmf = await player.playTone([697, 1209], 200)
-
-// Single frequency beep
-const beep = await player.playTone([440], 1000) // 440 Hz for 1 second
-```
-
-Returns: `Buzz.Playback`
-
-#### `player.playStream()`
-
-Create a streaming playback handle for real-time audio.
-
-```typescript
-const stream = player.playStream()
-
-// Write audio chunks
-stream.write(audioChunk1)
-stream.write(audioChunk2)
-
-// Check if buffer is empty
-if (stream.bufferEmptyFor > 1000) {
-  console.log("Buffer empty for 1+ seconds")
-}
-
-// Stop streaming
-await stream.stop()
-```
-
-Returns: `Buzz.StreamingPlayback`
-
-### Recorder
-
-#### `recorder.start()`
-
-Start recording to a stream.
-
-```typescript
-const recording = recorder.start()
-
-for await (const chunk of recording.stream()) {
-  // Process audio chunks (Uint8Array)
-  console.log("Received", chunk.byteLength, "bytes")
-}
-```
-
-Returns: `Buzz.StreamingRecording`
-
-#### `recorder.start(outputFile)`
-
-Start recording to a WAV file.
-
-```typescript
-const recording = recorder.start("./output.wav")
-
-// Stop when done
-await Bun.sleep(5000)
-await recording.stop()
-```
-
-Returns: `Buzz.FileRecording`
-
-## Types
-
-All types are available under the `Buzz` namespace:
-
-```typescript
-Buzz.AudioFormat        // { format?, sampleRate?, channels? }

-## Audio Format
-
-Default format: `S16_LE`, 16000 Hz, mono
-
-```typescript
-type AudioFormat = {
-  format?: string      // e.g., "S16_LE", "S32_LE"
-  sampleRate?: number  // e.g., 16000, 44100, 48000
-  channels?: number    // 1 = mono, 2 = stereo
-}
-```
-
-Common formats:
-- **Phone quality**: `{ sampleRate: 8000, channels: 1 }`
-- **Voice/AI**: `{ sampleRate: 16000, channels: 1 }` (default)
-- **CD quality**: `{ sampleRate: 44100, channels: 2 }`
-- **Professional**: `{ sampleRate: 48000, channels: 2 }`

-## Examples
-
-### Voice Activity Detection
-
-```typescript
-import Buzz from "./buzz"
-
-const recorder = await Buzz.recorder()
-const player = await Buzz.player()
-
-const recording = recorder.start()
-let talking = false
-
-for await (const chunk of recording.stream()) {
-  const rms = Buzz.calculateRMS(chunk)
-
-  if (rms > 5000 && !talking) {
-    console.log("🗣️  Started talking")
-    talking = true
-  } else if (rms < 1000 && talking) {
-    console.log("🤫 Stopped talking")
-    talking = false
-  }
-}
-```
-
-### Streaming Playback with Buffer Tracking
-
-```typescript
-import Buzz from "./buzz"
-
-const player = await Buzz.player()
-const stream = player.playStream()
-
-// Simulate receiving audio chunks from network
-const chunks = [chunk1, chunk2, chunk3] // Uint8Array[]
-
-for (const chunk of chunks) {
-  stream.write(chunk)
-
-  // Wait until buffer is nearly empty before requesting more
-  while (stream.bufferEmptyFor < 500) {
-    await Bun.sleep(100)
-  }
-}
-
-await stream.stop()
-```
-
-### Dial Tone with Voice Detection
-
-```typescript
-import Buzz from "./buzz"
-
-await Buzz.setVolume(0.4)
-
-const player = await Buzz.player()
-const recorder = await Buzz.recorder()
-
-// Play dial tone
-const dialTone = await player.playTone([350, 440], Infinity)
-
-// Wait for voice
-const recording = recorder.start()
-const vadThreshold = 5000
-
-for await (const chunk of recording.stream()) {
-  const rms = Buzz.calculateRMS(chunk)
-
-  if (rms > vadThreshold) {
-    console.log("Voice detected, stopping dial tone")
-    await dialTone.stop()
-    break
-  }
-}
-```
-
-### Play Sound Effects
-
-```typescript
-import Buzz from "./buzz"
-
-const player = await Buzz.player()
-
-// Play multiple sounds in sequence
-const sounds = ["./start.wav", "./beep.wav", "./end.wav"]
-
-for (const sound of sounds) {
-  const playback = await player.play(sound)
-  await playback.finished()
-}
-```
-
-### Background Music Loop
-
-```typescript
-import Buzz from "./buzz"
-
-const player = await Buzz.player()
-
-// Play background music on repeat
-const bgMusic = await player.play("./background.wav", { repeat: true })
-
-// Stop after 30 seconds
-await Bun.sleep(30000)
-await bgMusic.stop()
-```
-
-### Record to File
-
-```typescript
-import Buzz from "./buzz"
-
-const recorder = await Buzz.recorder()
-
-console.log("Recording for 10 seconds...")
-const recording = recorder.start("./output.wav")
-
-await Bun.sleep(10000)
-await recording.stop()
-
-console.log("Saved to output.wav")
-```
-
-### Multi-Device Setup
-
-```typescript
-import Buzz from "./buzz"
-
-// List all devices
-const devices = await Buzz.listDevices()
-console.log("Available devices:", devices)
-
-// Use specific devices
-const speaker = await Buzz.player("Speaker")
-const mic = await Buzz.recorder("USB Microphone")
-
-// Independent volume control
-await Buzz.setVolume(0.8, "Speaker")
-await Buzz.setVolume(1.0, "Headphones")
-```
-
-## Architecture
-
-### ALSA Backend
-
-Buzz wraps ALSA command-line tools (`aplay`, `arecord`) via Bun's subprocess API:
-
-- **Playback**: Spawns `aplay` with stdin pipe for streaming or file path for file playback
-- **Recording**: Spawns `arecord` with stdout pipe for streaming or file path for WAV output
-- **Volume**: Uses `amixer` for volume control
-
-**Benefits:**
-
-- **Simple**: No C bindings or FFI required
-- **Reliable**: ALSA tools are battle-tested
-- **Flexible**: Full format support (sample rates, channels, encodings)
-- **Portable**: Works on any Linux system with ALSA
-
-### Streaming Architecture
-
-Streaming playback uses Bun's subprocess stdin pipe:
-
-1. Spawn `aplay` with raw audio format and stdin input
-2. Write audio chunks to process stdin as they arrive
-3. Track buffer duration based on bytes written
-4. Calculate `bufferEmptyFor` using performance timestamps
-
-This enables:
-- Real-time playback of network streams (WebSocket, API responses)
-- Buffer management for smooth playback
-- Low-latency audio (<100ms with proper buffering)
-
-### Voice Activity Detection
-
-`calculateRMS()` computes the root mean square of audio samples:
-
-```
-RMS = sqrt(sum(sample²) / count)
-```
-
-This provides a simple but effective measure of audio energy:
-- Silence: RMS < 1000
-- Noise: RMS 1000-5000
-- Speech: RMS > 5000
-
-Adjust thresholds based on your microphone and environment.
-
-## Device Selection
-
-### By Default (Recommended)
-
-```typescript
-const player = await Buzz.player()
-const recorder = await Buzz.recorder()
-```
-
-Uses ALSA default device (usually correct).
-
-### By Label
-
-```typescript
-const devices = await Buzz.listDevices()
-// Find device with label containing "USB"
-const usbDevice = devices.find(d => d.label.includes("USB"))
-
-const player = await Buzz.player(usbDevice.label)
-```
-
-Useful for multi-device setups (USB audio, HDMI, headphones).
-
-## Error Handling
-
-```typescript
-try {
-  const player = await Buzz.player()
-} catch (err) {
-  if (err.message.includes("No playback devices found")) {
-    console.error("No audio output devices available")
-  }
-}
-
-try {
-  await Buzz.setVolume(0.5)
-} catch (err) {
-  if (err.message.includes("Failed to set volume")) {
-    console.error("Could not control volume (check mixer permissions)")
-  }
-}
-```
-
-## Troubleshooting
-
-### No devices found
-
-Check ALSA devices:
-
-```bash
-aplay -l  # list playback devices
-arecord -l  # list capture devices
-```
-
-### Volume control fails
-
-Check mixer controls:
-
-```bash
-amixer scontrols
-amixer sget Master
-```
-
-### Crackling or distortion
-
-Try different buffer sizes by adjusting format:
-
-```typescript
-const player = await Buzz.player(undefined, {
-  sampleRate: 16000,
-  channels: 1,
-  format: "S16_LE"
-})
-```
-
-### Device already in use
-
-Only one process can use an ALSA device at a time. Stop other audio applications or use PulseAudio/PipeWire for mixing.
-
-## Design Philosophy
-
-- **Simple by default** - `player()` and `recorder()` work out of the box without arguments
-- **Streaming-first** - Built for real-time audio (AI voice, telephony, WebRTC)
-- **Type-safe** - Namespace types provide autocomplete and compile-time safety
-- **Flexible** - Support for files, tones, and streams
-- **Minimal dependencies** - Uses standard ALSA tools, no native bindings
-
-## Performance
-
-- **Latency**: ~50-100ms for streaming playback (depends on buffering)
-- **CPU**: Minimal overhead (subprocess spawning + pipe I/O)
-- **Memory**: Efficient streaming (no need to load entire files)
-- **Voice detection**: `calculateRMS()` is fast (~1µs per chunk on modern hardware)

+# Bun FFI Learnings
+
+After researching GitHub examples and Bun's FFI documentation, here's what I found surprising and helpful.
+
+## Surprising Discoveries
+
+### 1. **String Handling is Simpler Than Expected**
+I initially thought you'd need `CString` everywhere, but:
+- For **args**: `FFIType.cstring` just needs `ptr(Buffer.from(str + "\0"))`
+- For **returns**: `FFIType.cstring` automatically converts pointers to JS strings
+- `CString` is mainly for **reading** C strings from pointers, not passing them
+
+**Example from real code:**
+```javascript
+const str = Buffer.from("hello\0", "utf8");
+myFunction(ptr(str));  // Clean and simple!
+```
+
+### 2. **No Type Wrappers Needed**
+Unlike Node-FFI, Bun doesn't require defining structs or complex type wrappers. Just:
+```javascript
+add: {
+  args: [FFIType.i32, FFIType.i32],
+  returns: FFIType.i32,
+}
+```
+
+### 3. **TinyCC JIT Compilation**
+Bun embeds TinyCC and JIT-compiles C bindings on the fly. This means:
+- 2-6x faster than Node-API
+- Zero build step for type conversions
+- Direct memory access without serialization
+
+## Helpful Patterns
+
+### Pattern 1: String Helper
+```typescript
+import { ptr } from "bun:ffi"
+const cstr = (s: string) => ptr(Buffer.from(s + "\0"))
+
+// Usage:
+gpiod.open(cstr("/dev/gpiochip0"))
+```
+
+### Pattern 2: Resource Cleanup
+Always use cleanup handlers:
+```javascript
+const cleanup = () => {
+  lib.symbols.release(resource)
+  lib.symbols.close(chip)
+}
+process.on("SIGINT", cleanup)
+process.on("SIGTERM", cleanup)
+```
+
+### Pattern 3: Destructuring Symbols
+```javascript
+const {
+  symbols: { functionName }
+} = dlopen(path, { /* defs */ })
+
+// Call directly:
+functionName(arg1, arg2)
+```
+
+## Common Mistakes to Avoid
+
+1. **Don't forget null terminators** - `Buffer.from(str + "\0")` not `Buffer.from(str)`
+2. **Pointer lifetime** - Keep TypedArrays alive while C code uses them
+3. **Type mismatches** - `FFIType.i32` vs `FFIType.u32` matters!
+4. **Missing cleanup** - C libraries don't have garbage collection
+
+## Best Practices from Real Examples
+
+1. **Use `suffix` for cross-platform library loading:**
+   ```javascript
+   import { suffix } from "bun:ffi"
+   dlopen(`libname.${suffix}`, { /* ... */ })
+   ```
+
+2. **Check for null on resource creation:**
+   ```javascript
+   const chip = lib.gpiod_chip_open(cstr(path))
+   if (!chip) {
+     console.error("Failed to open")
+     process.exit(1)
+   }
+   ```
+
+3. **Free configs after use:**
+   ```javascript
+   const config = lib.create_config()
+   // ... use config ...
+   lib.free_config(config)  // Don't leak!
+   ```
+
+## What Makes Bun FFI Special
+
+- **Performance**: JIT compilation beats traditional FFI
+- **Simplicity**: No build tools, no gyp, no node-gyp nightmares
+- **TypeScript native**: Works seamlessly with TS type system
+- **Built-in**: Ships with Bun, zero dependencies
+
+## Hard-Won Lessons from GPIO Implementation
+
+### 1. **Enum values MUST match the C header exactly**
+We spent hours debugging because our constants were off by one:
+```typescript
+// WRONG - missing GPIOD_LINE_BIAS_AS_IS
+export const GPIOD_LINE_BIAS_UNKNOWN = 1  // Actually should be 2!
+export const GPIOD_LINE_BIAS_DISABLED = 2 // Actually should be 3!
+export const GPIOD_LINE_BIAS_PULL_UP = 3  // Actually should be 4!
+
+// CORRECT - includes AS_IS at position 1
+export const GPIOD_LINE_BIAS_AS_IS = 1
+export const GPIOD_LINE_BIAS_UNKNOWN = 2
+export const GPIOD_LINE_BIAS_DISABLED = 3
+export const GPIOD_LINE_BIAS_PULL_UP = 4
+export const GPIOD_LINE_BIAS_PULL_DOWN = 5
+```
+**Lesson:** Always grep the header file for the complete enum, don't assume!
+
+### 2. **Hardware debouncing requires correct constants**
+With wrong constants, we were accidentally passing `BIAS_DISABLED` instead of `BIAS_PULL_UP`, which meant:
+- No pull resistor (pin floated)
+- Debouncing didn't work at all
+- Got 6+ events per button press
+
+After fixing: **Clean single events with 1ms debounce via kernel!**
+
+### 3. **Edge detection is event-driven, not polling**
+Don't poll `get_value()` in a loop! Use:
+- `gpiod_line_request_wait_edge_events()` - blocks until interrupt
+- `gpiod_line_request_read_edge_events()` - reads queued events
+- Much more efficient, CPU sleeps until hardware event
+
+### 4. **TypedArray to pointer needs `ptr()`**
+When passing arrays to C functions:
+```typescript
+const offsets = new Uint32Array([21])
+gpiod.gpiod_line_config_add_line_settings(
+  lineConfig,
+  ptr(offsets),  // Need ptr() wrapper!
+  1,
+  lineSettings
+)
+```
+
+### 5. **Signal handling for clean shutdown**
+Generators don't run `finally` blocks if abandoned. Need:
+```typescript
+let shouldExit = false
+process.on("SIGINT", () => { shouldExit = true })
+
+while (!shouldExit) {
+  const ret = wait_edge_events(request, 100_000_000) // Use timeout!
+  // ...
+}
+```
+
+### 6. **Button wiring determines logic**
+- **GND button + pull-UP**: Press = FALLING edge (HIGH→LOW)
+- **VCC button + pull-DOWN**: Press = RISING edge (LOW→HIGH)
