Objective Tune Audyssey calibration tool

Developed by: H. Murat Fertelli · Objective Audio

What is it for? Upload the calibration file (.ady) saved by the Audyssey MultEQ Editor app of your Denon/Marantz AV receiver. From your measurements we rewrite each channel’s measurement data as the main-seat response to be corrected (peaks cut fully, room-mode dips left alone) and prepare 4 corrected files (Normal, Hpy and the Bass+ version of both) plus a report. The correction is made for your main listening seat.

Required: the Audyssey MultEQ Editor app. It creates the .ady file and loads our corrected files back into your receiver. Install it on a phone or tablet (App Store / Google Play, paid) on the same Wi-Fi as the receiver; a calibration made from the receiver’s own menu cannot be used.

How to use

  1. Install Audyssey MultEQ Editor and start the calibration from the app. Measure at least 3, preferably 6–8 microphone positions; position 1 must be your main seat.
  2. In the app go to Files → select your file → Share / Export and send the .ady file to yourself. Keep the original.
  3. Sign in and upload the file below. Optionally add REW measurements taken with a calibrated microphone (Umik etc.) and choose Live+ or hearing support.
  4. When the report is ready, download 1- Normal first, open it in MultEQ Editor via Files → Import and Transfer it to the receiver. Keep the sound mode on Audyssey “Reference”.

Upload your calibration file

Do not change the receiver settings for the measurement. Leave Small/Large, crossovers, distances and the subwoofer mode as the calibration left them; turn off only MultEQ, Dynamic EQ and Dynamic Volume. Name the measurements after the channels (L, R, C, SL, SR, …, LFE). If an error is detected, your measurement is not used: the result is calculated from the .ady alone and the report says why. Typical errors: measured with our file or Audyssey on; microphone not at Audyssey position 1; wrong channel names. Not every error can be detected; an undetected one can make the result worse.

Sound preferences (optional; uses 1 more credit: with 2 credits in total you also get 5- Normal and 6- Hpy with this setting, 6 files. Without it you get 4 files for 1 credit; Bass+ versions are always included)

Advanced options (Dynamic EQ, manual crossover)

Crossover (manual)

Empty channels are chosen from the main-seat measurement (60–120 Hz). A value you enter is used as is; “Large” makes the speaker full-range.

Room dimensions (cm, recommended)

What happens next? Analysis starts automatically after upload (a few minutes). Objective Audio checks the report before release; when it is ready we e-mail you (if your account has an e-mail) and you can always find it under “Your reports” on this page. Report links do not expire; download links are valid for 30 days.

What you get

  • 4 corrected .ady files (Normal, Hpy, Normal + Bass+, Hpy + Bass+) for the main seat. Hpy: 90–180 Hz +3 dB, centre/surround/height channels a little forward. Bass+: gentle shelf below 150 Hz, +5 dB at 30–50 Hz.
  • Safe mode (V1.1): only EQ changes. Crossovers, speaker size (Large/Small), distances and subwoofer settings stay as Audyssey set them. In any channel and frequency band where our predicted result is worse than Audyssey’s, Audyssey’s own correction is kept.
  • Direct main-seat correction: Audyssey corrects the average of all seats; we rewrite each channel’s measurement data as the main-seat response to be corrected (the method A1 Evo also uses), so the app corrects the main seat directly. Before you get the files we simulate the app’s calculation and re-check the result up to 3 times.
  • Peaks and dips (full band, up to 20 kHz): peaks are cut fully. Dips that are likely room modes or reflection cancellations (narrow, present in several channels, only at the main seat, or showing a delayed reflection in the impulse response) are left alone; other dips are boosted by at most +6 dB (+3 dB below the speaker’s natural bass roll-off). Subwoofers are corrected the same way.
  • Report: room modes, reverberation, reflections, subwoofer crossover and the reason for every setting.

Frequently asked questions

Which receivers are supported?

Denon and Marantz AV receivers with Audyssey MultEQ XT32 / XT that work with the MultEQ Editor app; all channels in the file, from 5.1 up to 9.4.6 and 11/13-channel models. The channel layout is never changed.

How is the crossover chosen?

Audyssey’s crossover and speaker size (Large/Small) are kept as they are. You can enter crossovers manually in Advanced options; a value you enter is written to the file.

What does the extra Umik measurement add?

The Audyssey microphone is not calibrated. Channels measured with a calibrated microphone at the main seat (after the calibration, MultEQ off) use that measurement; the microphone difference is compensated and distortion is taken into account.

How much does it cost?

Followers of our YouTube channel or Instagram get 1 measurement report and free Objective Tune calibrations (limited-time campaign). Each report or calibration then uses 1 credit; Live+ or hearing support uses 1 more credit and adds 2 files. If the analysis fails the credit is refunded.

Can I get new files with different options?

Yes. On your report page use “Prepare again with new options” to change Live+ / hearing support, Dynamic EQ and crossovers with the same measurement (1 credit; 2 with Live+ / hearing support).
