With the promise of convenience and quality, online mastering services have been a hit with independent producers. But while most services bank on processing via digital algorithms, Aria is aiming to do something novel by offering high-grade, all-analogue mastering undertaken by a robotic arm.

The arm is an integral cog in Aria’s mastering process, designed to make precise tweaks on high-end analogue audio equipment such as Manley’s Massive Passive Stereo Equalizer, Pendulum Audio’s Variable Mu 6386 Tube Limiter and more. To kick start the machine-mastering process, all you have to do is upload a mix and make selections across mix type, EQ, as well as output levels.

Aria further adds that its service runs 24/7 and masters your tracks in real time. Pricing for the service comes in three tiers, detailed below:

  • Single master: $19 per song
  • Artist subscription: $49 per month, capped at 10 songs
  • Project subscription: $99 per month, capped at 25 songs
  • Professional subscription: $249 per month, capped at 100 songs

If Aria delivers on its high-grade audio promise, the inclusion of intelligent machinery could well prove to be an exciting development in online mastering.
