Why streaming ops decode AAC to WAV?
Aggregators and music distributors still ask for PCM intermediates so loudness meters, true-peak limiters, and QC scripts run on predictable linear data. Teams bounce AAC references from hosts while mastering engineers still want WAV before the final AAC or FLAC consumer file. Searchers type aac to wav podcast loudness, spotify lufs wav, true peak meter, apple podcasts mastering, and encode generation notes because rejections cite numbers, not vibes. Decoding does not auto-pass -16 LUFS myths—each platform updates guidance, and inter-sample peaks still bite after decode. Chapters and JSON sidecars remain separate concerns from the PCM file itself. ISRCs and publishing metadata do not fill themselves when bytes become WAV. Ai2Done keeps the stream-ready variant honest: read current specs, measure integrated loudness and true peak, disclose AAC lineage in delivery notes, and keep dual checksums when portals bounce files.
How to prep AAC for streaming measurement workflows
- Open AAC to WAV, choose the streaming-ready variant, read the latest loudness and peak guidance for the target DSP or podcast host, and confirm required sample rates.
- Decode, run approved meters, adjust limiting upstream—not by random attenuation—then upload sandbox episodes or tracks until automated QC passes.
- Publish delivery notes that say decoded-from-AAC, attach tool versions, and archive both AAC and WAV checksums when rejections require proof you did not clip in transit.
