About This Tool

The tool converts input audio into raw PCM samples suitable for downstream DSP, analysis, or real-time audio engines. It accepts common formats, decodes them to uncompressed numeric samples, and writes them as linear PCM data.
Conceptually, it follows a two-step path: decode to an internal PCM representation, then optionally resample, mix channels, and adjust endianness and bit depth to match the requested output. Output is a plain binary PCM file with accompanying attributes describing rate, channels, and depth.
Who benefits: audio engineers, researchers, and developers who require deterministic, metadata-free samples for precise analysis or integration into engines. Unique value arises from multi-format decoding, explicit PCM parameter control, and safe, lossless PCM paths when possible. Core features include input format support, parameterized sampling, and robust validation for PCM output.
Typical use cases include DSP algorithm development, audio feature extraction, game audio pipelines, and academic experiments that demand consistent, uncompressed samples.

How to Use

  1. Provide inputs by uploading audio_file and selecting target PCM parameters.
  2. Choose sample_rate (Hz), channels (1/
  3. , bit_depth (8/16/24/
  4. , and endianness (little/big) as needed.
  5. Run conversion to generate the raw PCM output.
  6. Download the output file and verify its properties (rate, channels, depth).
  7. If needed, re-run with adjusted parameters for different pipelines.

Frequently Asked Questions

Find Quick Answers

Which input formats are supported?
The tool decodes common formats such as WAV, MP3, FLAC, AAC, and OGG using open-source decoders integrated into the pipeline. Support may vary by build, but core formats are consistently available for PCM output.
What is raw PCM output?
Raw PCM is uncompressed, linear audio data without a header, typically accompanied by metadata describing sample rate, channels, depth, and endianness. It is suitable for immediate processing by DSP tools and engines.
Can I set the sample rate and channels?
Yes. You can specify target sample_rate and channels. If omitted, the tool preserves the source rate and channels where feasible or performs a safe conversion to the requested configuration.
Are metadata preserved?
No. The conversion outputs pure PCM samples and ignores metadata from the source file. If metadata is required, extract it separately before or after conversion.
