I'm using a Samsung tab S7 and it seems like like everything was going fine until I went to save the effect setup and my project, however it would not save. The app has all the storage permissions it needs to work, it just doesn't seem to on my device. I was able to export what I was working on, but since I'd still have to start my presets from scratch every time I start a new project I opted for a refund.

Unbelievably powerful in a light easy to use package. I've paid 50x more for desktop apps and this does 98% of the same thing for a fraction of the price, and can do it any time and any where. I'm still not great at mastering, it's an art form that takes a good ear and understanding of music production, but at least now I have the proper tool for it.

I got this to convert wave to MP3. It does. So I can take my musical creations from caustic to the world if I want. I bought Caustic for 10 bucks ages ago. It was awesome from the start. It's gotten better and better. You could master something properly. I'm a hobbyist really. I'm amazed at how much I've learnt about music. Simple to use yet gratifyingly complex. I cannot say enough how awesome Caustic is.

I just downloaded it today; I'm really looking forward to playing around with this app to polish up my beats. Typically, I'd use the default mastering section inside Caustic, but this one has the compresssor, exciter, and gain staging function that most top mastering software would include. BTW, I heard there's a version for PC. I have to check it out.

Anyone who gives this app fewer than 5 stars simply doesn't understand what it's made to do or how powerful it is. This is literally a complete mastering package for Android for pennies compared to what you'll pay for a DAW and then an Izotope mastering package or the like. If you're familiar with Caustic, you'll be right at home here (and it interfaces great with Caustic, too!). If you're interested in mastering audio or just want a great DSP effects suite, look no further. Bravo! More!!

I like the concept, but i hate the fact that when i export the song, their is a loop at the end. For example when the song ends, it replays the beginning of the song for like 10, to 15 seconds. Also, their is always a static noise in the song for some reason.

Great tool, not had the problems of looped bits on the end. I'm on a fairly new Motorola g6. Louder final mixes without distortion. Comment about ability to delete fx... Took me a moment, but swipe fx down to switch off or carry on dragging to the bottom to delete.

This is a mastering wonder that fits in your pocket. As with any software, you have to know what you are doing. The fact that it gives you full control of the sound makes it very professional. Works great even on devices with low ram and older processors. Keep up the great work! Producer Gino Love.

Hi, i just want to inform you, the WAV file of this app is not working on kinemaster video editing app, i wrote email also, but you people give not any response, please fix it, it will be a great help. Thanks.

This app is very powerful. I polished my mix in a DAW then use caustic to make it shine. Every song is different and you don't need to over do it. Just a touch of this and a touch of that.

I am unable to export my songs nomatter what bitrate or file types I choose, and sharing, uploading to Dropbox instantly fails every time. I'm using the app on an S10+ with Android 10.

Exports a few seconds of ontro after outro ends. 2 stars because it sounds great. Needs an update badly. I have to use a wav editor to cut off excess everytime all the while losing my reverb tailed endings. LG K51

Mic. H. Jan 21, 2022     

i have zero idea why anybody would give this less than 5 stars. excellent tool for anybody doing mobile production and honestly the first thing i would reccommend to anybody trying to learn how to master. if it doesnt sound As good as a 5 thousand dollar protools setup, it at least laughs its face in terms of value. this is a no brainer. thx dev

Bak. C. Jul 18, 2020     

Because of zero reaction or even a resemblens of recognition of this obvious problem, mentioned even by many others, down to 1 star till you fix the bug! Old review: It renders/exports and some, again from the beginning. Without this glitch it's a 5 star!

Myk. D. Nov 23, 2020     

First it worked quiet nice but now it won't export the entire song anymore. It cuts off after about 60% of the song length so it is now no longer usable for me. Too bad I have paid for this.

Lei. W. May 17, 2019     

An intuitive, powerful mobile mastering app cramed with all the functionality needed for a better sound. Highly recommended.

Gra. P. Jun 3, 2019     

So glad this has now been released, it's the perfect way to polish those mobile masterpieces. Packs a lot of punch in an easy to use UI.

I bought the app and the play store just asks me to buy again when I try to install. When I do try and buy it again it says I already own the product. Any help with this would be great.
