Sound You Can See !

Sound View is an Audio Spectrum Analyzer & Spectrograph App. It analyzes sound from the built in microphone, or from the Line in input device, and displays the results in three separate views.

The waveform view displays the raw input signal as a continuous wavy line, where each wave is a pulse of sound.

The spectrum view displays the frequency distribution as vertical bars, each bar represents a group of frequencies, the height indicating the strength of those frequencies within the audio signal.

The spectrogram view displays a two dimensional view of audio spectrum frequencies, over time. Each pixel represents a group of frequencies, it's color indicates the strength of those frequencies. The vertical rows represent different frequencies, and the horizontal columns represent time.

Frequencies range from 0 hertz to 22050 Hertz or 22K, this is half the sample rate of 44100 audio samples per second. That is the same sample rate as a compact disc audio recording.

Since it uses the microphone, it works well with iTunes. Any sound the mic can pick up is analyzed and displayed, so you can play music on your computer, or use a different sound system and see the frequency distribution, spectral density, and waveform.

Full screen display is available for each of these three views. Select the View menu item, then Full Screen Display, or you can use the Command-F keystroke. This will put the key or active window into fullscreen display mode. You can return to the windowed view by hitting the escape key.

In the waveform view, you can dynamically adjust the display width and height. The spectrum view allows similar adjustments, but you can also drag the display left and right, to see the frequencies that interest you.

The spectrogram view has controls for color intensity, and vertical zoom. It also allows you to drag the display up and down to see desired frequencies.

You can record a spectrogram for later viewing too. By selecting View -> Recording Control Panel you can start and stop recording and save your data.

Application Help is availble from the main menu under the Help item, and also from the help button on the preferences panel.

Enjoy The App !!

Version 1.2.0
Review by chopter1

Very nice app for the price - I am a comm systems engineer and wanted a cheap spectrum analyzer to check out the spectral content of some songs. This was exactly what I was looking for. The only thing missing was the ability to select internal sources as some of the other reviews said. I decided that for the price, it wasn't worth deducting a star. That said, the displays are very nice to look at, especially the flames option of the spectrum view. The controls are basic but sufficient for zooming to the audio spectral region I want to look at. The windows are fully scalable which is nice to tile it to fit your screen. It seems very stable so far. Kudos to the developer.

Review by yakingcat

Waste of $ Cannot use any other audio interfaces. - Do you really trust your sound analysis to the built in Mic or Line Input?! Why can't we select any valid audio in? Terrible.

If you could change the source, it would be a perfect app! - My title says it all, except to say, this is what I have been hoping Apple would release as a visualizer for iTunes. However, it must be noted that one nice thing about this app is it is not limited to being used with music or podcasts, as an iTunes visualizer would be. Compared to other spectrum analyzers that cost 10 times more, this is even better than those apps, so consider it a no brainer if you are looking for a spectrum analyzer. Just be aware that the source will be the mac’s microphone.

Version 1.3.5
Review by RobS813

No free demo - Had to pay for this up front (OK it was only 2.99, but still…) only to find out it would not do what I was looking to do - actual RTA of an incoming audio signal with the ability to measure a particular frequency.
