ToneBoosters Spectrogram shows a real-time spectrogram, spectrum, and goniometer AUv3 plugin! We have taken the stunning visual spectrum analyzer features from our latest and greatest Equalizer Pro plugin and released it as a separate app / AUv3 plugin! The ToneBoosters Spectrogram app captures the microphone input and processes the signals in real time. To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others. ToneBoosters Spectrogram will appear in the list of Audio Unit extensions for effect plug-ins. Key features: - Fully resizable (as AUv3 plugin) - Color themes for the user interface - Max screen support in Garageband - Adjustable color themes for UI and for spectrogram independently - Adjustable dynamic range - Adjustable frequency resolution - Adjustable time resolution - Adjustable spectral slope - Spectrogram AGC and dimming support - Show spectrogram and spectrum analyzer as overlay or individually - Spectrum analyzer also supports peak hold - Split-band goniometer for stereo signal analysis (correlation, left/right balance in one or two bands!) - On-screen piano keyboard to map spectrum analyzer to piano notes - Optimised for iPad and compatible with iPhone and iPod Touch What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models. }

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 . 🙏🙏🏿👍😄

Great quality spectrogram. UI is not usable on iPhone (the buttons are too small) but you get a spectrogram already on opening the app.

really helpful app when it comes to trying to recreate songs with MIDI or to use it as a reference.

Love the piano keyboard on the right to link highlighted frequencies to specific notes, and worked brilliantly for me for visualising some music theory. I play bass guitar and would love to be able to zoom in vertically. I appreciate that I might not get any better resolution (as the frequency bins at the bass end are probably quite wide) but it would help fill the screen and make it easier to match to notes.

Another great tool from a solid & reliable company!!!! I love that we are finally seeing analyzers for iPad if I could make one small suggestion a spectrogram is a powerful tool but a waveform display would be a great option as a in app purchase. This would make it easier to mix on an iPad if we could see if the waveform of a master is is too squashed or too dynamic especially after long sessions when your ears become fatigued. 5 Stars.

My review title sounds like pasta with some doggy cheese on top but I am actually referring to frequencies in a mix which sometimes shouldn’t be there. This app is of great assistance during eq actions in weeding out those head space gobbling gremlins ..fab app 👏👏👏🙏 🎩🦄📡
