Why batch AAC to WAV for podcast operations?
RSS round-trips, ad agency VO drops, and synthetic voice libraries often land as hundreds of tiny AAC files while your Reaper template insists on one sample rate. Searchers type batch aac to wav, podcast stems wav, sample library sample rate, loudness batch because manual DAW exports do not scale across forty episodes a season. Batch horror stories are boring but expensive: track nine accidentally mono, duplicate basenames overwrite each other, and sleep mode truncates half the queue without a log line. Spreadsheets should lock default language stems, bit depth, mono fold rules, and retry policies before automation touches thousands of files. Disk forecasts matter—linear PCM multiplies bytes faster than AAC ever did. Copyright clearance does not get cheaper when a robot runs the decode. Ai2Done keeps the batch variant accountable: golden triples first, checksum manifests after, failed rows quarantined instead of silently skipped.
How to batch decode AAC to WAV without silent corruption
- Open AAC to WAV, choose the batch variant, build a CSV with source paths, targets, languages, and sample rates, then read aggregate caps.
- Process three pilot episodes through loudness scripts and ear-check sibilance and channel maps before you let the queue run overnight.
- Diff file counts and total bytes, attach manifest hashes to the ticket, and route failures to a quarantine folder with explicit error text—never overwrite happy-path outputs blindly.
