SPECTRUMVIEW

Visualise, in real time, the frequencies that you can hear around you and even those you cannot. SpectrumView provides a high-quality, real-time spectrogram and spectrum analyser display, with a configurable sample rate and frequency resolution for the iPhone, iPad and iPod Touch. You can use this application to measure the highest tones you can sing, obtain visual feedback of the frequencies in your speech, identify an annoying sound, calibrate musical instruments and all sorts of acoustic analysis.

· *NEW* Refresh Spectrogram. Allows users to refresh the spectrogram so that it clears the spectrogram that had already been displayed.
· *NEW* Change min and max scale. Allows users to set their own minimum and maximum scale value on the spectrogram and spectrum analyser view, in both linear and log scale.
· *NEW* Set Recording filename. Recording filenames are editable and the suffix can be set to have an incremental value or date/time.
· *NEW* Access recordings and snapshots using the "Files" app. To ease the complicated process of accessing recordings and data snapshots using iTunes, all the data can be easily accessible using the "Files" app that is available from iOS 11.
· Web File Transfer. Allows you to access your files from another device using a web browser.
· Logarithmic scale. Allows you to set either linear or logarithmic frequency scales in the Spectrogram and Spectrum Analyser views
· Peak hold. Allows you to freeze and hold the peaks of the frequency envelope (three holds in three distinct colours) in Spectrum Analyser mode
· Save location. Never forget where a clip was recorded – uses the devices location services
· Auto lock disabled. During playback and recordings auto lock is disabled to prevent the device from automatically locking (if enabled), for uninterrupted recording/playback
· Multiple selectable sample rates from 8,000 Hz to 48,000 Hz
· High-frequency resolution with configurable signal analysis window lengths or Fast Fourier Transform (FFT) orders.
· Sound intensity represented using a colour spectrum scale from -96 dBFS to 0 dBFS.
· Frequency Pinch-to-Zoom. Allows you to zoom into the frequency space to look at a specific tone or frequency.
· Recording and Playback of Audio Files. Provides a fully functional audio recorder that allows you to record, pause and play back files in high-quality, uncompressed, wave format.
· Tap Data Cursor. Allows taps on any part of the Spectrogram or Spectrum Analyser display to obtain the exact frequency in Hertz (Hz) and level in decibels (dB) at that point.
· Musical Notes or Frequency Display on Tap. Selectable frequency or musical pitch notation to obtain the cent-accurate musical note e.g. A4 (22), when the display is tapped.
· Live Spectrogram and Spectrum Analyser Views of Recorded Files. Files recorded can be played back and the Spectrogram and Spectrum Analyser modes can be used to review the audio.
· Sharing Recorded Files by Email or iTunes File-sharing.
· High Quality Screenshots.
· Soundcloud support. Audio files can be uploaded to or downloaded from Soundcloud as well as being able to post audio to facebook.
· Playback from iTunes library. Files can now be analysed directly form the iTunes library.
· Fullscreen mode. Hide the menu at the bottom of the screen to get even more of the screen dedicated to frequency analysis.
· Selectable spectrogram colour scales. You can now select one of 7 colour scales for your spectrogram.
· Selectable window functions. You can now see the window function options provided.
· Apply gain. A maximum of 24dB gain can be applied to make ‘hard to see’ details easier to view.
· Open In. Audio files can be directly opened in SpectrumView. View files sent by email directly in SpectrumView.

Tolle App, aber...

Eine wirklich tolle App. Leider vom Design und auch der Skalierung auf hochauflösenden Displays um Jahre hinterher, aber die App arbeitet genau und bietet im Gegensatz zur Konkurrenz auch Aufnahmen an: Top!

Aber - was mich am meisten stört: Warum wird der Start der App durch die Einblendung und unnötige "Animation" des Logos so verzögert? Ein schnelles spontanes Aufzeichnen oder Analysieren eines kurzen und kurzfristig Auftretendem Störgeräusches ist auf diese Weise nie möglich. Genau dazu nutze ich die App: Störquellen zu finden. Manchmal sind es aber Töne, die nur kurz und unregelmäßig auftreten - um diese aufzuzeichnen eignet sich die App aufgrund des künstlich verlangsamten Starts der App nicht. Da arbeiten Apps der Konkurrenz weitaus schneller, meist sogar "sofort" nach Start der jeweiligen App. Bitte schaltet doch diesen Ladebildschirm ab - da muss gar nichts so lange geladen werden.

Funktioniert perfekt!!!

Funktioniert perfekt, dafür dass es gratis ist. Das mit abstürzen kann ich gar nicht bezeugen. Aber dazu: das ist eine App die wahrscheinlich sehr viel Leistung zieht und deswegen wäre es vllt hilfreich andere, noch nebenher laufende Apps komplett zu beenden.
