SignalScope update supports audio mixing on iOS

SignalScopeIcon60@2x

 

SignalScope Pro 6.1 and SignalScope 7.1 have been released for sale on the App Store with some important enhancements, including the ability to mix audio output with other apps. Audio mixing means that it is possible to play music from the Music app while performing signal analysis with SignalScope or SignalScope Pro. It is also possible to mix the output of the signal generator* with the audio output from another app.

The SignalScope apps include other important enhancements:

  • The FFT analyzer tool now supports frequency resolution as fine as 0.1 Hz for audio input signals.
  • When working with an iPhone or iPad that has multiple built-in microphones, the unique name of the selected microphone is displayed (e.g. “Bottom Microphone” or “Right
    Microphone”).
  • When analyzing two input channels in the Octave tool, both spectra are displayed in a single line plot.

SignalSuite for iOS now sports a fresh UI and support for larger iPhone screens

SignalSuiteAppIcon120Version 1.5 of SignalSuite, the original stereo audio signal generator for iPhone, finally supports larger iPhone screens, including those of the new iPhone 6S and 6S Plus, with a fresh new look. Functionally, the new version of SignalSuite is equivalent to previous releases, although it is now possible to manually select from a list of available audio output routes (e.g. the iPhone speaker or an Apple TV on the local network). The user interface elements have been updated to be consistent with the changes made to the appearance of iOS since version 7.

IOScope 3.0 Updated for iOS 7

As in recent updates to SignalScope Pro and SoundMeter, IOScope’s appearance has been completely revamped for iOS 7. IOScope supports both iOS 6 and iOS 7, but looks largely the same on iOS 6 as the previous version.

Also new in version 3:

– Audio data handling is more efficient.

– For devices that support input gain adjustment on the built-in or headset microphone, the input gain is stored with exported data.

– When entering a preferred sample rate, “48k” can be entered in the text box, as an alternative to typing out “48000.”

– Default input sensitivities have been updated, based on measurements of the iPhone 5S and 5C microphones and headset inputs.

– Cursor info text now uses a larger font.

Octave Analyzer tool for iOS

 

The Octave Analyzer tool for iOS performs real-time spectral analysis in whole or 1/3-octave frequency bands.

The Octave Analyzer tool is built into SignalScope Pro. It is also available in SignalScope and SoundMeter via in app purchase.

The Octave Analyzer can analyze up to two audio input channels simultaneously (this requires a two-channel input device).

The Octave Analyzer can be configured with several options that are common to overall sound level meters. These options include time weighted exponential average levels with fast, slow, and impulse response times as well as the equivalent level, which expresses an average signal level over the total measurement time. Flat, A, and C frequency weighting are also available.

The Octave frequency spectrum appears within a bar graph which can be adjusted in its vertical scale either manually or automatically. In addition to current levels within each frequency band, maximum or peak levels may also be displayed, depending on which level type is selected. A data cursor allows specific levels at specific frequencies to be identified. The entire graph can be saved either as an image in the iOS photo library, or as a high resolution PDF file within the app.

Additionally, in SignalScope Pro, Octave analyzer data may be exported to CSV, MAT, or tab-delimited text files. Data export is also possible in SignalScope and SoundMeter with the optional Data Acquisition Upgrade available via In-app Purchase.

Stereo 1/3-octave analysis now available in SignalScope Pro

With the release of version 2.2, the Octave tool in SignalScope Pro for iOS can now analyze two input channels simultaneously. This new capability is only available on devices running iOS 5 or later, and it requires a stereo or two-channel dock connector audio accessory.

     

The Octave tool offers whole and 1/3-octave real-time spectral analysis with A, C, or flat frequency weighting and fast, slow, or impulse time weighting. Time exponential averaged level (Lp) and equivalent level (Leq) measurements are both supported.

The Octave tool available via in-app purchase in SoundMeter 3.0 and SignalScope 3.2 also offers two-channel measurement capability on iOS 5 or later. SoundMeter 3.0, SignalScope 3.2 and SignalScope Pro 2.2 are all available for immediate download on the App Store.

Improvements in SignalScope 3.2 and SignalScope Pro 2.2 include:

  • For users running iOS 5, or later, the Octave analyzer tool can now be operated as a stereo RTA, analyzing two input channels simultaneously (with compatible input hardware). (The Octave tool is available within SignalScope via in-app purchase.)
  • Data can now be exported to CSV files from the FFT, Octave, and Oscope tools. CSV files can be opened directly in Numbers, or other spreadsheet apps that support it, from within SignalScope. Tab-delimited text files can still be created by giving the file name a .txt extension. (Data file export requires the data acquisition upgrade available within SignalScope via in-app purchase.)
  • Corrects a potential crash when accessing the image picker on iPad.
  • SignalScope uses less memory on iPhone and iPod touch.
  • Twitter support has been restored (in iOS 5) for tweeting level meter data. (The Level Meter tool is available within SignalScope via in-app purchase.)

SoundMeter 3.0 offers in-app upgrades

  SoundMeter 3.0 is now available for download on the App Store,

offering in-app purchases of the same tools found in SignalScope Pro. Available upgrades include dual-channel Octave RTA, Oscilloscope, and FFT Analyzer tools, as well as a data acquisition upgrade.

Dual-channel analysis in the Octave tool enables SoundMeter to be used as a stereo 1/3-octave RTA. This dual-channel capability requires iOS 5, and is also coming soon to the Octave tool in SignalScope and SignalScope Pro, but it is available now in SoundMeter. (In SignalScope, the Octave tool is also available via in-app purchase.)

SoundMeter’s new data acquisition upgrade enables the user to export Octave, Oscope, and FFT data to CSV, tab-delimited text, and MAT files, and to access those files from a web browser on another device. This upgrade also enables additional units, such as V, A, g, and ips to be assigned to input signals.
