Incredible app

Holy cow, this app is great! Simple and powerful. I love interface of being able to touch the screen and see what notes are what. Love this app, great job to whoever made this.

Very good and improving!

The core functionality was always great - for me, it was the UI that needed some finesse. The last two updates have gone a long way towards making this the GOAT. I have but do not use 3 or 4 other spectrogram apps.

Honestly, given the insistence on ultra small and narrow font (understandable given the real estate issues, but sometimes it feels excessive… nobody can read 2 pt. Arial Narrow) even making the menu close ‘X’ bigger would help.

realtime color spectrum in ULTRASONIC, not here!

haven’t you dev’s heard of color? like red for too loud? blue for low level? green for mid level? yellow for high input? I couldn't delete this fast enough but i did notice all the pricey apps and plugins. I guess most reviewers here thought so too. And no trials?? (good luck selling anything)

Absolutely brilliant at revealing nasty low and high-frequency content and therefore facilitating targeted shelving . 🙏🙏🏿👍😄

Please give me an option use to audio files.

I don’t know where the option to use them even is.
