About This Tool

The AAC/FAAC Decoder decodes AAC/FAAC streams into PCM samples for analysis, debugging, and verification of audio processing workflows. It targets audio engineers, researchers, and QA teams who need verifiable, reproducible decoded output from compressed streams.
Conceptually, the tool treats the input as a bitstream, parses frame headers, and feeds frames to a decoder core to produce 16-bit PCM samples. It supports common container formats such as ADTS, ADIF, and RAW bitstreams, and can optionally override the output sample rate and channel count to suit downstream analysis or resampling workflows.
Distinctive value comes from automation-friendly inputs (base64 payloads), explicit metadata (duration, sample rate, channel count), and predictable PCM output without requiring proprietary players. It is designed for integration into testing pipelines, performance benchmarks, and regression checks across decoding paths.
Core features include input validation, frame-accurate decoding to PCM, and export options (base64 PCM or WAV). Typical use cases include validating decoders, auditing bitrate effects on decoded output, reproducing decoding errors, and supporting research into codec behavior.

How to Use

Provide inputs: supply base64-encoded AAC data and declare the input_format (ADTS, ADIF, or RAW).
Configure outputs: optionally set sample_rate and channels for the PCM output. Validate any overrides against your downstream requirements.
Run decode: trigger the decoding process to generate PCM data and metadata.
Review outputs: inspect PCM data, duration, sample_rate, and channel_count; download PCM as base64 or WAV if needed.
Export and validate: store the PCM payload and associated metadata for downstream analysis or regression testing.

Frequently Asked Questions

Find Quick Answers

What formats are supported?

The decoder supports ADTS, ADIF, and RAW AAC bitstreams. LATM handling is limited to header-based parsing; non-AAC codecs are not supported.

What outputs are produced?

Outputs include PCM data in 16-bit little-endian format, plus metadata such as duration_ms, sample_rate, and channels. PCM can be returned as base64 or WAV export depending on integration.

Is LATM/LOAS supported?

LATM parsing is supported at a header level where feasible; complete LATM framing might require additional configuration or be limited by the input stream.

Is encrypted AAC decoded?

No, the tool does not decrypt DRM-protected or encrypted AAC streams; it operates on non-protected bitstreams.
