Awful company, shysty practices, they trick you into a yearly subscription and lock you in, if your bank has no money they wait till it does and take it, disgusting from a supposedly reputable company, the service itself isn't even good, fake promises, I learnt to master my own music which sounds a thousand times better than their "AI" It's awful they get away with it.

everyone there is a scam, mf should go to jail immediately

Scam, Shady Business Tactics. Avoid.

Paid for an annual subscription. I cancelled the service (Received confirmation that it will not renew at the end), and they proceeded to renew the subscription anyway and tell me that I cannot be refunded for the unauthorized renewed subscription. These people are shady and do not run an honest or legitimate business.

Use Landr, instead. it sounds and works better, and they run a much stronger and more honest business.

I used their service twice and i am disapointed.
On the first song i didn't like the mastering quality.It saw only louder and a little brighter.
On the second song was the same story.I tried to get my money back and it was not possible.
Now i get it.Music is personal and it is made by humans for the humans.
I found out that mixing and mastering ,nowdays,is a lot cheaper that in was 20 years ago
So i payed 20 or 25 $ for a real mastering and Voila.I got what i wanted a master that not only sound louder but is deeper sweeter,creamier.
I found on fiverr website a very good engineer called cata 546 and after this themixbros.com a dedicated studio for this.I am very impressed not only by the quality but also that i was able to tell the engineers what i was after and also they even advised me a little bit on the mixing aspects of music.

they stole my money, offering 14 days of trial, the service is bad, so I canceled it the same day, they never returned the money and they did not give the proportional fee, they are thieves, DO NOT USE IT EVER. if I didn't cancel the annual plan with paypal they would still be charging me
