Audiofile DDP Player
DDP Review & Master Approval
Free
Open branded Audiofile DDP masters from your engineer, review CD-Text and meters, then send timestamped feedback by email.
Audiofile DDP for iPhone and iPad is the free review app for .audiofileddp master deliveries.
When your mastering engineer sends a branded Audiofile DDP bundle, open it from Files, Mail, AirDrop, or Messages and review the actual DDP master on your device.
Built for artists, labels, A&R, producers, and mastering clients who need to hear and approve the final disc master before replication.
Review workflow:
- Open signed Audiofile DDP delivery bundles
- See album art, artist info, studio branding, and the engineer's welcome note
- Play the delivered DDP master with gapless transport
- Review track titles, durations, CD-Text, ISRCs, UPC/EAN, indexes, and timing
- Send timestamped feedback directly to the mastering engineer by email
Final-check tools:
- CD-rate native DDP playback through the iOS audio system
- Peak/RMS VU-style metering
- EBU R128 LUFS: Momentary, Short-term, Integrated, and Loudness Range
- Goniometer / vector scope with stereo correlation
- Waveform overview and scrub-to-seek navigation
- Mini transport so playback continues while browsing the library
Audiofile DDP does not require an account. The app is free for recipients, so mastering engineers can send a master without asking clients to buy software, enter a serial number, or follow a long setup process.
Audiofile DDP is built by Audiofile Engineering, makers of professional audio tools since 2004.
