Description

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 !!

What's New in Version 1.2.0

★ Logarithmic Scale for both Spectrum and Spectrograph Displays. You can now see the lower frequencies in greater detail by enabling the logarithmic scale in both spectrum and spectrograph view, you can select from 128 to 16 bars for the spectrum and the same choices for spectrogram height.

★ Freeze Display ability for all 3 views.

★ Minor Bug Fix, if you moved your pictures directory to another directory or drive, the app will no longer crash when saving spectrogram recordings.

★ Minor Bug Fix, Spectrogram Recording Control Panel is now only available if the Spectrogram Window is active.

★ New Icon.

Customer Reviews

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.

Nice Little App for the Price

it works, i mainly wanted it for the spectrum analyzer part which comes in handy. The program had no problems using the USB mic pre connected to my MacBook Pro, very convienent.
A couple suggestions would be tailor the display for audio people, meaning add the graph lines (like in the waveform view) and segregate the horizontal axis per typical audio analyzers (i.e., 20 Hz, 100 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, 16 kHz, 20 kHz) so that the view is typical of most RTA and FFT systems. It can be used as is, and I do, but it would be helpful if it was a little more compliant with audio realm standards.

Missing obvious and trivial feature.

This needs a source selector, so that you can select whatever audio your computer is playing as the source, rather than only the microphone that's hooked up to the input. This feature would be trivial to implement, so when I bought it, it didn't even occur to me that it wouldn't have this feature. If they did implement this feature, it would get five stars, but the app is crippled without it.
