Haaze provides two different ways of making a mono (or a not-wide-enough-stereo) signal to a wider stereo signal.
By splitting the input signal into 16 different frequency regions, spanning from 20 Hz to 20kHz, Haaze can add different amount of stereo-widening to different frequency regions. This makes it possible to transform a mono track into a natural sounding stereo track (by for example keeping lower frequencies in mono while spreading the higher ones).
Haaze is using two different stereo widening techniques, Haas (short delays between left and right channel) and ”Split EQ” (different gain on different channels on different frequency regions).
• AUv3, works with AUv3 compatible hosts like Cubasis, Auria, AUM etc.
• 16 separate frequency regions with independent parameters on each band
• Two different stereo widening algorithms (Split EQ and Haas)
• Convenient and easy-to-use user interface
To apply the Haas effect, click and drag the spring component horizontally. The top-most part applies the effect on higher frequencies, and the bottom-most part applies the effect on lower frequencies.
To apply the ”Split EQ” effect, drag the LOW (bass frequencies), MID (mid frequencies), HIGH (high frequencies) sliders to apply the effect.
The MIX knob mixes the input audio with the processed audio.
NOTE: When setting the MIX knob somewhere in the middle, there might be noticeable phase issues (if so, we recommend setting the value to max and adjusting the other parameters instead).
Important: Haaze in stand-alone mode does not support IAA, Audiobus. You can try it out using the microphone, but beware of audio feedback (use headphones!). We recommend using Haaze with AUv3 compatible hosts.
Sydney-based electronics manufacturing and software development company, Sinusoid released this handy little app way back in 2010, which provides sound professionals and audio enthusiasts alike access to a set of audio measuring and testing software tools, that replace the dedicated hardware typically required to get the same results.
Audio Kit has enjoyed regular updates ever since its launch, with the latest upgrade to version 2.0 delivered in April this year. One of the key new features in 2.0 is the introduction of a sweep generator, which is available as an in-app purchase for US$0.99.
This clever new feature aims to take the labour out of manually testing a wide range of frequencies one by one for potential problems in a range of audio environments. For example, a front-of-house sound engineer could quickly and easily find any rogue frequencies in a PA system, by putting the sweep generator through the system and listening out for any problem frequencies that jump out. To aid in pinpointing any rogue frequencies visually, the sweep generator can be activated while using the spectrum analyser mode.
For a full rundown on the Audio Kit, here’s the media release announcing version 2.0
Sydney, Australia – Sinusoid Pty Ltd today is proud to announce the release of Audio Kit 2.0 for iOS including New sweep generator (IAP). Audio Kit is a collection of four tools which are essential for those working in audio, sound and music; A real time Spectrum Analyser, a Scope to display waveforms, an SPL Meter, and a Signal Generator producing sine waves, white noise and pink noise and sweep generator (with IAP). Users can view a real time spectrum of audio, identifying peak frequencies. In-App purchase now provides a sweep generator. The Audio Kit iOS App has been used by many sound professionals and enthusiasts for sound monitoring since 2010.
Audio Kit Features:
* New – Sweep generator available as In-App purchase
* View a real time spectrum of audio with the Spectrum Analyser and identify peak frequencies precisely
* The Signal Generator provides a sine wave output up to 20,000Hz in 1 Hz steps, along with noise generators for white and pink noise and sweep (IAP)
* View the actual waveform of the audio signal with the Scope
* An SPL Meter provides measurement of sound levels using an A-weighting. Calibration of SPL Meter
FFT (Fast Fourier Transform) is used to calculate the frequencies in the Spectrum Analyser of Audio Kit and these are displayed in real time. The frequency is displayed in either logarithmic or linear scale.
* Three FFT sizes of 8192, 4096 and 2048 are selectable, giving fine resolution of frequencies
* 6 different FFT window function types can be selected – Hamming, Hann, Rectangular, Bartlett, Triangular and Blackman
* Number of FFT windows can be selected from 1 through 4
The strongest frequency is displayed both above the peak, and optionally, in a large number display in the center of the screen. The large number display can be quickly switched on or off by double tapping the screen.
There is a screen capture facility in the Spectrum Analyser allowing you to save the spectra for future reference along with details of the FFT parameters, time and date.
A single tap freezes the screen. Other features such as screen capture and double tap to toggle large number display still work during the freeze. This feature can be turned off in preferences if it’s not desired.
The display of the Scope can be adjusted easily using pinch gestures in both horizontal and vertical directions. Zero crossing detection of the waveform provides a smooth display and can be set to either positive or negative direction zero crossing. There is a screen capture facility in both the Spectrum Analyser and the Scope allowing you to save the spectra and waveforms for future reference.
The SPL Meter of Audio Kit continuously displays the sound pressure level, and has resettable minimum and maximum displays also. There is also a colored bar type indication of the measured SPL at the left hand side of the screen. A sliding ticker type plot of the SPL readings over time is displayed across the bottom of the SPL screen. If the reset button is pressed the peak registers a mark of full scale then zero. The SPL Meter can be calibrated against a reference SPL meter or a reference sound source.
The output of Audio Kit’s Signal Generator can be viewed on the other parts of the App. The Signal Generator has 3 different output types:
* Sine wave
* White noise
* Pink noise
* Sweep Generator (from In-App purchase)
The output of the Signal Generator can be viewed on the other parts of the Audio Kit App. The sine wave frequency selected using picker wheels allows for accurate control of frequency to within 1Hz. Volume for the sine wave and noise signals is continuously adjustable. Output is in both left and right channels.
The sweep generator of Audio Kit allows a sweep or chirp of audio frequencies anywhere in the audio range. Sweep direction can be either increasing or decreasing and can be set to be linear or log in output. Very short chirp times can be produced.
All of the user preferences in each of the above applications can be made persistent between restarts of the App. All parts of the App have direct access to a detailed context sensitive help document.
New features for version Audio Kit 2.0
* Added availability of in-app purchase for sweep generator capability for Signal generator
* Reverted to 2 channel output for all Signal Generator outputs
* Idle timer can now be disabled if auto lock is enabled on device – This allows user to run the app for long periods unattended without going into lock mode
* Minor bug fixes
* Update for recent iOS releases
* Requires iOS 7.1 or later
* 1.7 MB
Pricing and Availability:
Audio Kit 2.0 is $2.99 USD (or equivalent amount in other currencies) and available worldwide exclusively through the App Store in the Music category.

SPL Graph is an audio Sound Pressure Level (SPL) environmental noise analyzer, real-time frequency analyzer, chart recorder and data logger. It includes:
* Plot sound level over time
* Record audio while plot is running
* Capture video of events
* Do octave and 1/3 octave band analysis
* Show a 3D Plot of octave or 1/3 octave results
* Calculate Ln SPL values, L01, L10, L50, L90, L95, LMax and LMin
* Email notifications when sound exceeds pre-set limits
* Auto-save results after set intervals, and email the results to you
* Start another plot after auto-saving for continuous operation
SPL Graph Pro includes all in-app purchase options, including octave logging and video capture.
SPL Graph works by averaging the SPL for a period of time that can vary from 0.1 second to 60 minutes, applying an optional weighting filter, and plotting the sound level, recording the raw audio signal, if recording is turned on.
For sound intervals of 1.0 second to 60 minutes, the optional octave and 1/3 octave logging modules allows storing the spectrum of the sound, for each interval.
The app works very well with the built-in iOS device microphone. To upgrade the app to true professional standards, add our iTestMic, iPrecisionMic, or iAudioInterface2 with an appropriate microphone, and get ANSI or ISO Type 1 or 2 results. With iPrecisionMic, you can actually send the system in to our calibration lab and get a calibration certificate for ISO 61672 and ANSI S1.4.
SPL Graph can record up to 24 hours of sound level data, with single second resolution. The graph starts with a one-minute plot window, and as a minute is recorded, the graph re-scales automatically and adds another minute to show the data collected so far. The overall SPL level, or LEQ, is displayed for whatever portion of the test is showing on the graph.
Tap the play button to play back the recorded audio, and you can use the cursor to scrub the audio location on the graph. Use this feature to listen to events that you can see on the graph.
With the octave logging module, you can also record the octave or 1/3 octave band levels. And, you can view the data on the 3D plot for a graphical view of frequency over time.
You can scroll and scale the graph vertically, in dB, by using standard swipe and pinch gestures. You can also scroll and expand and contract the time axis using gestures. Zoom out to a full 24 hours, or zoom in to a single minute, showing second resolution. Double-tap the screen to zoom out to show the entire graph on the screen.
The time scale grid changes dynamically, highlighting minutes, ten-minute, and hour lines as as it runs.
As the graph runs, the overall LEQ (average SPL) for the entire time period is computed and displayed on the screen. Swiping across the graph brings up a cursor that displays the exact dB level and time for any point on the graph.
You can turn on audio recording, so that you have a record of the sounds that were happening while the graph was being stored. You can use this to figure out exactly what the sound was that caused a peak on the graph, for example. Recordings can be compressed or uncompressed.
SPL Graph supports saving graphs directly on your iOS device. You can recall these graphs and bring them up on the screen, and listen to the sounds that were made while the graph was recorded. You can also store an image of the screen to your photo roll. Use Dropbox or iTunes Files Sharing to export the results to your computer.
You can also export data in tab-delimited files for XLS import. Dropbox is supported for automatic file transfer.
The filters are all ANSI type 1 or better, and include A-weighting, C-weighting, and all octaves band filters from 32 to 16kHz.
Pretty straightforward description below, but lets face it we all know what to expect from this app, and as far as EQs go, this is a nice addition to your workflow.
zMors EQ is an audio unit v3 effect plugin.
