glint_audio

Dart FFI bindings for the glint codec suite.

The package exposes MP3, AAC-LC and Opus encode/decode APIs, whole-file decode and encode helpers, WAV read/write helpers, and a Kaiser-windowed sinc resampler. It loads the native glint library at runtime:

• Linux and Android: libglint.so
• macOS: libglint.dylib
• Windows: glint.dll
• iOS: symbols from the process image

This package does not ship prebuilt native libraries. Build or bundle the native library from the glint repository for the target platform before using the Dart bindings.

Usage

import 'dart:typed_data';

import 'package:glint_audio/glint_audio.dart';

final pcm = Float32List(48000 * 2); // interleaved stereo, +/-1.0

final opus = glintEncodeAudio(
  pcm,
  2,
  48000,
  GlintCodec.opus,
  bitrate: 96000,
);

final decoded = glintDecodeAudio(opus);
final wav = glintWriteWav(decoded.pcm, decoded.channels, decoded.sampleRate);

For lower-level streaming APIs, use GlintEncoder, GlintAacEncoder, GlintOpusEncoder, GlintOpusDecoder, GlintMp3Decoder and GlintAacDecoder.
