What AppTrendKit can say about TB Spectrogram today

Evidence history

Collected daily performance

No daily metric history has been persisted yet.

No backfilled days
Daily metrics will appear here after the estimator has persisted more than one observation.

Rank history

Observed chart positions

Lower rank is better. Only collected observations are shown.

No positive rank observations are stored for this storefront yet.

Coverage note

What the ranks mean

A missing rank is not treated as zero downloads or zero revenue. Apple chart feeds are bounded and may return censored or not-ranked observations outside the visible chart depth.

What the store says

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.
