audio_processing

Stateful, provider-neutral PCM processing utilities for Audio Kit.

The package includes resampling, downmixing, rechunking, metering, timeline synchronization, mixing, and WAV encoding. Transform state is isolated per track so chunk boundaries do not introduce gaps or reset resamplers.

import 'package:audio_processing/audio_processing.dart';

final meter = AudioMeter();
final reading = meter.process(frame);

File-backed WAV recording is opt-in because it uses dart:io:

import 'package:audio_processing/audio_processing_io.dart';

See the Audio Kit repository for pipeline examples.
