The Spectrograph displays and records real time spectrograms (visual representations of the spectral density over time) by processing the audio signal from the microphone input (or any external microphone connected to the input jack) or any digital audio input via the dock connector (if suitable external hardware is connected). It offers a 2D view and an amazing 360 degrees fullscreen 3D view.

Use the Spectrograph for studying music, animal sounds, voices and speech or just have fun with the beautiful visualization of environmental sounds! Make use of the ability to store and load spectrograms and even reprocess them with different settings for discovering new details in your recordings!

Spectrograph features:
- 2D view with control panel for record, free run and store
- 3D view (free run only) with touch gesture controls of the viewing angle
- free choice of bandwidth and number of frequency bands (depending on device up to 800!)
- 3 buffer sizes: 1024 / 2048 / 4096 samples
- 3 gain modes for getting the best out of every acoustical situation
- 6 different color schemes
- logarithmic time frequency scale (detachable)
- record spectrograms (recording time between 30 seconds and 2 minutes - depending on your device)

Absturz ios 9.0.2

Liebe Entwickler, ich würde das tolle programm gerne unter meinem neuen Iphon6s mit ios 9.0.2 verwenden. Ohne Headset wird kein Signal erkannt. Mit Headset wird ein Singnal erkannt, die App stürzt aber nach wenigen Sekunden ab

Sehr coole App

Ich bin sehr zufrieden, ist nicht nur hilfreich, sondern macht auch bei meinen Kunden großen Eindruck. Habe das iPad beim Recording und Mischen neben dem Monitor stehen. Bin echt begeistert. Sieht beeindruckend aus und das ganz ohne Kabelsalat.
