SPL Graph Pro

Posted by Mikers On August - 11 - 2016 ADD COMMENTS

screen520x924 (1)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.

Smart Sound Meter

Posted by Mikers On July - 10 - 2016 ADD COMMENTS

Maybe of interest to anyone wanting to know more about SPL monitoring (for free) –

screen480x480Sound Meter (SPL – sound pressure level) is an app which can measure the actual sound level meter with decibels (dB). Sound meter is also known as sound level meter, decibel meter (dB meter), noise meter, sound pressure level meter (spl meter).

It uses your built-in microphone and shows a reference. We had calibrated many android devices with the actual sound level meter with dB.

You have to know that the built-in microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are limited by the hardware limitation, and very loud sound (100+ db) cannot be recognized.

Remember that it’s only a device for fun and please use it as an auxiliary tool.

Levels of Noise In decibels (dB) according to American Academy of audiology:
140 dB – gun shots, fireworks
130 dB – jackhammers, ambulance
120 dB – jet planes taking off
110 dB – concerts, car horns
100 dB – snowmobiles
90 dB – power tools
80 dB – Alarm clocks
70 dB – traffic, vacuums
60 dB – normal conversation
50 dB – moderate rainfall
40 dB – quiet library
30 dB – whisper
20 dB – leaves rusting
10 dB – breathing

M/S Proc – Mid/Side Level & EQ

Posted by Mikers On June - 9 - 2016 ADD COMMENTS

screen480x480M/S Proc is a tool for M/S Processing that enables Mid/Side level adjustments and EQ.

***What is M/S Processing?***
While standard audio processing is done through the Left and Right(L、R) channels, M/S processing divides elements into those at the center(Mid) and those on the left or right(Side). For example, it allows you to adjust the effect of the centrally located vocals or make nuanced changes to the width of the mix.
In addition, tracks with sound pressure levels raised to the maximum in stereo processing can often be found to have additional headroom in the Sides when separated into M/S elements. This means you can increase the sound pressure just by enhancing the Sides.
M/S Proc allows individual level adjustment and EQ processing for Mid and Side channels.

***Main features***
+ Mid/Side level adjustment.
+ Mid/Side EQ control with three bands (High, Mid, Low). The Mid is a parametric equalizer.
+ In addition to standalone usage, compatible with Audiobus and Inter-App Audio. Can be combined with other apps.
+ Can adjust sounds brought in from external devices and apps. Also works with WAV and AIFF formats.
If applying to files, you can export your processed tracks as a WAV file.
Exported files can be exported to other apps using the “Open In” function.
+ Also lets you import files from other apps (“Open In” function)
+ You can also import tracks from your Music Library.
+ Presets allow you to save your parameter settings in the file.
+ A universal app that can be used with both iPhone/iPad.

***Other uses***
Although M/S processing is most often used for mastering, in principle by lowering the Mid you can apply a “center cancel.” In this way you can prepare tracks for karaoke or “learning by ear.”
We also recommend sending your file to mimiCopy, our “learning by ear” music player app.

MiniReview – Pro Series EQ Plug-ins

Posted by Mikers On June - 9 - 2016 ADD COMMENTS

EQ-Series-1San Diego-based purveyor of pioneering music software and hardware, Positive Grid, has released a fresh suite of effects plug-ins, which are built on the company’s revolutionary analog sound modelling tech smarts and component level customisation.

Following on from the release of its Pro Series Studio Compressor plug-ins earlier this year (and reviewed here), Positive Grid has just launched a follow-up collection of professional sounding effects, this time focusing on EQ plug-ins designed to work with all major DAW software, and available in VST, RTAS, and AAX native formats.

The new trio of EQ plug-ins provide a similar palate of tonal themes as the suite of compressors, in that there is a Tube EQ, Digital EQ, and Passive EQ plug-in.

Harnessing the same technology already found in Pro Series Studio Compressor plug-ins, not to mention its BIAS amp modelling software, Positive Grid’s new Pro Series Studio EQ suite is designed to deliver the unique sonic differences between tube, digital and passive EQ, through the use of analog filters to replicate the familiar frequency response of hardware based EQ counter parts in the real world. The company claims this ‘EQ Match’ process is made possible by analysing both the input track and side chain signals, and by detecting the difference between the two, it automatically adjusts the EQ parameters to match the different curves. So it will be interesting to see if we see some updates in the future that are ‘sound-a-likes’ of famous brand EQ products, since it sounds like it possible to replicate almost any audio source.

Another of Positive Grid’s unique additions is component level customisation of the EQs. This feature is not nearly as extensive here as found on the compressor plug-ins, but there are still switchable pre-amp tubes on two of the EQ plug-ins, which is not something you can expect to find on most EQ plug-ins.

DIGITAL-EQThe first in the suite that I fired up was the Digital EQ, which its creator describe as ‘the most clear and transparent digital EQ sound ever in a plug-in’. The overall sound is definitely pure in quality, with and interface much akin to a 5-band parametric EQ. The plug-in displays a left and right side of dials, and each of the sweepable bands of EQ has individual gain and Q curve control dials. There also independent high pass and low pass control, plus main input, output, and balance controls. You can also unlink the left and right sides if one of the sides need independent EQing. The top of the interface displays a live frequency display of the input signal, along with an EQ curve showing the adjustments you’ve made to the sound. This is a great feature that can be found on all three plug-ins. Overall this the more straightforward and honest sounding EQs of the three, which worked well on the vocal, and acoustic guitar tracks I tested it on.

PASSIVE-EQThe next plug-in I looked at was the Passive EQ. Positive Grid say this is your go-to EQ if you’re after ‘an authentic analog sounding EQ for a more musical mix’.  There is definitely plenty of control here to add extra colour to your sound. This three-band EQ offers 4 preset frequencies per band, ranging from 32Hz to 58kHz. The Q curve dial works in a similar way, offering three bell curves from wide to narrow, plus a high and low shelf setting. Where the additional colour can be applied, is though the tube pre-amp section, which features the classic 6L6GB and EL34 vacuum tubes. By adjusting both the input and output gains, you can drive the tubes hard or soft to get the desired sound you like. As with this tube emulation feature on Positive Grid’s other software, it’s great how these glow brighter and pulse in time with the audio signal, the harder they are working. I found this EQ sounded great on drum mixes, bass guitar, and backing vocals, but I certainly wouldn’t limit its uses for just these.

TUBE-EQThe last in the trio, and my personal favourite, is the Tube EQ. Not only do I really like the sound of it, but the overall functionality, as well as the great vintage style visual design. Positive Grid claim this EQ ‘captures  the  essence  of analog EQ found in the best professional studios in the world,  giving you the ultimate solution to add color and warmth’. I can attest that of the 3 plug-ins, this offers the more interesting EQ parameters by far. Unlike the previous 2 EQs in the suite, the Tube EQ is split across two main areas that you switch between, the Hi/Lo and Mid EQ controls. The concept and controls are not unlike that found on the legendary Pultec EQs, where you have a boost and attenuation dial for these main bands of EQ. And it’s this unique ability to merge and mangle both the bump and dips in the EQ that makes this plug-in fun to play with. The low band offers preset frequencies to cut or boost from 20Hz to 220Hz, while the high band frequencies start at 3KHz and go right up to 160KHz. There’s also independent low and high cut dials, with sweepable frequency ranges. Flipping over to the mid EQ controls, you’re presented with three customisable bands for the mid-range. Each band has individual balance control, a bandwidth control to adjust the shape of the Q curve, and then a preset dial of frequencies, starting at 220Hz up to 48KHz, spread across the three bands. The interesting way they work  is, the dials on the left are designed to boost frequencies between 220Hz to 1KHz, and the dials on the right picks up at 1.2KHz through to 48KHz, while the dials in the middle attenuates frequencies from 360Hz to 100KHz. I’m sure it’s possible to replicate the same crazy EQ patterns made here on the other plug-ins in the suite, but for me it’s just more enjoyable operating this one. The final important feature is the inclusion of three different pre-amp tubes, that emulate the popular 12AU7, 12AT7, 12AX7, which can be used to give the EQ settings some extra colour and warmth. Unlike the Passive EQ, though there is no input or output control on this pre-amp stage. One other small thing to note about the Tube EQ is, it’s the only one of the three that doesn’t allow independent EQ control of the left and right signals. This isn’t a major issue besides, the majority of EQ plug-ins don’t offer this anyway.

As I’ve said the Tube EQ actual design is great, but the other two look good two, and they’ve all been designed to look photo realistic, like real world hardware.

As with the suite of compressors, the Pro Series Studio EQ plug-ins come with a pretty disappointing list of just three factory presets per plug-in, and of course the ability to save your own presets. Though as with the compressor suite, Positive Grid says we can expect a growing list of downloadable EQ profiles created by music industry professionals to be available, but The Pro Series EQ Plug-Ins are now available for download on the Positive Grid store for $99. the is no word on when this might be.

While it’s fair to question, does the music world really need another suite of EQ plug-ins, when there are literally dozens and dozens already out there that do a great job. I will say, Positive Grid has at least come at it from a fresh angle, with their EQ Match technology, and added pre-amp tubes for extra control. As with all plug-ins and software in general, it comes down to personal choice. So if you like the way any product sounds, functions, and looks, and it gets the job done, then it’s the right product for you.

The Pro Series EQ Plug-Ins are now available for download on the Positive Grid store for $99.
