SoundMeter and dB support new iPads

Nominal microphone sensitivities for the iPad Air and iPad mini with Retina display have been added to SoundMeter 4.0.1 and dB 3.0.1.

Both apps also display dark blue toolbars in the black color scheme to make it easier to view the screen in dark environments.

SoundMeter additionally corrects the HTTP file server configuration screen, which now scrolls to reveal the web URL on 3.5-inch iPhone screens (the file server is available for in-app purchase as part of the data acquisition upgrade).

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.

Also new in version 3:

– Audio data handling is more efficient.

– Image overlays created in the Level Meter tool now use the full resolution of the original image (whether the image comes from the photo library or straight from the camera).

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

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.

SignalScope and IOScope support sample rates up to 192 kHz

Current versions of SignalScope (3.6.2), SignalScope Pro (2.6.2), and IOScope (2.5) include advanced audio configuration options that support user selection of the audio sample rate. Using built-in iPhone and iPad audio hardware, this typically means that sample rates as low as 8 kHz can be selected. Since the iPad additionally supports external USB audio devices, via the iPad Camera Connection Kit or the Lightning to USB adapter, sample rates as high as 192 kHz can be made available with the right hardware. Which sample rates can be selected depends on values supported by the connected audio hardware.

Typical sample rates for the built-in microphone or headset input of current iOS devices include:

  • 8 kHz
  • 11025 Hz
  • 12 kHz
  • 16 kHz
  • 22.05 kHz
  • 24 kHz
  • 32 kHz
  • 44.1 kHz
  • 48 kHz

It is possible to sample audio data at up to 192 kHz, with USB devices that support it, on iPad. One such device is the Echo 2 from Echo Digital Audio, which supports sample rates of:

  • 44.1 kHz
  • 48 kHz
  • 88.2 kHz
  • 96 kHz
  • 176.4 kHz
  • 192 kHz

SignalScope, SignalScope Pro, and IOScope are all available for download on the App Store.

The Echo 2 is available from B&H Photo Video and from Amazon.

Input triggering now available in the FFT analyzer on iOS

SignalScope 3.5 and SignalScope Pro 2.5 for iOS have arrived on the App Store with added support for input triggering in the FFT spectrum analyzer tool. Triggering support essentially matches that in the Oscope tool, including Auto, Normal, and Single-shot triggering modes, positive or negative slope triggering, and a user-definable input level threshold.

Also new in these apps is a 1 second per division time scale in the Oscope tool that enables up to 10 seconds of time data to be visible in the Oscope display.

Pop those balloons with RoomScope 1.3

A common request for RoomScope has been to directly capture room impulse response (IR) data using impulsive noise sources, such as balloons or starter pistols. RoomScope 1.3 now supports both single-channel and dual-channel IR data acquisition. The dual-channel capability has been built-in since version 1.0 of RoomScope, enabling the use of an omnidirectional loudspeaker and various excitation signals including broadband noise and frequency sweeps. The new single-channel IR acquisition tool can capture IR data directly by popping a balloon or firing a starter pistol within an acoustic space of interest. The input signal can be triggered in order to automatically begin data acquisition when the instantaneous input level crosses a user-defined threshold.

It should be noted that single channel analysis doesn’t mean that only one channel of data can be captured at one time. In fact, with an iPad and a multi-channel USB audio interface, it is possible to capture IR data from multiple microphones simultaneously (obviously, the mics and supporting cables, adapters, etc, would also be needed). Single channel analysis simply means that each input channel is treated independently from all other input channels. In contrast, dual-channel analysis means that a single measurement is based on data acquired from two input channels (using auto and cross-spectral analysis).

RoomScope 1.3 is now available for download on the App Store.

Room acoustics comes to the Mac in Electroacoustics Toolbox 3.2

Have you been looking for a tool to measure the reverberation time, early decay time, clarity and definition of a listening room, auditorium, or concert hall on your Mac? With version 3.2 of Electroacoustics Toolbox, the search has come to an end. Within Electroacoustics Toolbox 3.2 you will find a new room acoustics analyzer tool (sold separately) that puts room acoustics analysis in your grasp.

The new Room Analyzer tool in Electroacoustics Toolbox employs the integrated impulse response method to calculate reverberation time, early decay time, center time, clarity, and definition, as defined in the ISO 3382 standard. The Room Analyzer also allows you to adjust the Schroeder decay curve integration limits with either a click and drag of the mouse or with two independent data cursors. You can plot the calculated room acoustics parameters versus whole or 1/3-octave band center frequency.

Room Analyzer Features:

  • Directly analyze impulse response (IR) data acquired in the Dual FFT Analyzer or Oscilloscope tools.
  • Import impulse responses acquired from other apps and stored in AIF, CAF, or WAV audio files.
  • Export calculated parameter values to CSV, TXT, or MAT files, with the option to include raw IR data.
  • Save impulse response (IR) data to AIF, CAF, or WAV audio files.
  • Save high-resolution plots to PDF files.
  • Analysis
    • Calculate room acoustics parameters according to ISO 3382, including T20, T30, T60, EDT, Ts, C50, C80, D50, and D80, over the entire audio frequency range, or in whole or 1/3-octave bands. Low, mid, and high frequency values for each parameter are also calculated.
    • Plot room parameters versus whole or 1/3-octave center frequency.
    • See the Schroeder decay curve and regression line plotted over the squared IR and manually fine tune the decay curve integration limits.

For whole and 1/3-octave band analysis, the Room Analyzer supports data with sample rates of 44.1 kHz or 48 kHz.

Electroacoustics Toolbox 3.2 also brings back the Noise Dosimeter tool that was previously available in version 2. The Dosimeter tool is also sold separately.
