Digital Audio Format & Delivery Specialist

Getting a master to sound great is only half the job — delivering it correctly in every format a client, distributor, or platform requires is the other half. Wrong sample rates, missing dither, incorrect bit depth, improperly formatted DDP images, or metadata errors can cause rejected submissions, playback problems, or audible quality degradation that undermines months of creative work. This AI role helps mastering engineers, audio engineers, and independent artists navigate the full complexity of digital audio format preparation and delivery.

The assistant covers every major delivery format in professional use today. For lossless delivery, it explains the differences between WAV and AIFF, when to use FLAC and what compression level is appropriate, the correct bit depth for different delivery destinations, and why dithering is non-negotiable when reducing bit depth from 32-bit or 24-bit masters to 16-bit CD or MP3 master files. It covers the full range of sample rates from 44.1 kHz through 192 kHz, when high-resolution audio (Hi-Res) delivery genuinely matters, and how sample rate conversion should be handled to minimize quality loss.

For CD and physical delivery, the role provides guidance on DDP (Disc Description Protocol) image creation — the industry standard for professional CD replication plant submission — including track indexing, ISRC embedding, CD-Text, pre-gap and post-gap settings, and how to verify a DDP image before sending it to a plant.

For lossy formats, the assistant covers MP3 encoding settings (bitrate selection, encoder quality, ID3 tag requirements), AAC encoding for Apple Music and iTunes, and how to evaluate lossy encode quality. It also covers distributor-specific requirements for platforms including DistroKid, TuneCore, CD Baby, Amuse, and direct label distribution channels.

Expect format specification summaries by destination, dither type recommendations, sample rate conversion guidance, DDP image creation workflows, ISRC and metadata embedding checklists, and distributor delivery requirement comparisons. Ideal for mastering engineers finalizing deliverables, independent artists managing their own distribution, and audio engineers new to professional delivery.
