This is a tutorial on how to use the REW acoustic measurement program to make in-room measurements of your home theater system. This guide will teach you what you need to assemble a cost effective and highly accurate room analyzing system using your PC, free license of REW, a USB powered microphone and accessory cables. We go over the various measurement options REW offers and how to use them effectively to make accurate measurements.

The d&b NoizCalc software uses international standards to model the far field noise immission from one or more d&b loudspeaker systems. NoizCalc takes data from the ArrayCalc simulation software and calculates snapshots showing the sound propagation and relative attenuation values towards the far field for a certain scenario with particular meteorological conditions. With these tools, the optimal sonic experience is delivered reliably and faithfully to the right ears, and not the wrong ones.
The results are displayed on a 3D terrain map showing the calculated immission on the areas surrounding the audience listening zones. This visual representation shows the actual system performance in the far field, enabling users to optimize for listeners while satisfying local noise restrictions and offsite regulations. To ensure the results are reliable, NoizCalc includes all complex data concerning the addition and subtraction of sound waves, including phase information to describe the combination and interaction effects within a loudspeaker system consisting of multiple line arrays, subwoofer arrays and delay systems.
NoizCalc models immissions in the far field according to the internationally accepted ISO 9613-2 and Nord2000 calculation standards. Ground characteristics can be set depending on the absorbency or reflectivity of surfaces, while areas with volume attenuating properties can be defined. Buildings can be included, and the maximum reflection order option adjusts how many reflections are calculated. Parameters for humidity, air pressure and temperature ensure that the correct air absorption figures are accounted. The ISO 9613-2 standard requires limited meteorological information and assumes a worst case scenario. The more sophisticated propagation model, Nord2000 enables a more precise handling of meteorological conditions allowing the user to model with prevailing wind information. d&b NoizCalc was developed in collaboration with SoundPLAN, a specialist software developer for environmental noise prediction.
In the studio with Zeitgeist Audio Mastering as we compare some of the best Software plugin Compressors closely with Hardware… A guide to learning to listen to what that Mojo is all about… including carefully crafted audio samples to download from several different genres. Also some Pro Mastering Tips thrown in along the way by seasoned Mastering Engineer – Nicholas D’Ombrain – as he guides you through this test…
This comparison is all about the samples – to accurately compare, very good headphones and or monitors combined with a quality Soundcard / DAC are strongly advised…. As the differences are subtle… In may help you in deciding whether or not to stay in the box or to go for that more expensive hardware…
Here is the link to download the Ableton Live Set with the samples embedded for easy listening & accurate comparison:

The Live Set is set-up for you so that you can easily switch between 6 different genre samples.
As stated in the video,
Press 1 (on keyboard), to listen to the Normalised Sample
Press 2, to listen to the Tegeler Audio VTC Sample with Mild Processing (HARDWARE)
Press 3, to listen to the Tegeler Audio VTC Sample with Medium Processing (HARDWARE)
Press 4, to listen to the PSP Master Compressor Sample with Mild Processing (SOFTWARE)
Press 5, to listen to the Waves API2500 Compressor Sample with Mild Processing (SOFTWARE)
Press 6, to listen to the Softube Tube-Tech CL 1B Compressor Sample with Mild Processing (SOFTWARE)
Press 7, to listen to the Elysia Xpressor Sample with Mild Processing (HARDWARE)
Press 8, to listen to the Elysia Xpressor Sample with Medium Processing (HARDWARE)
Press 9, to listen to the Sample Mastered by Zeitgeist Audio Mastering (Combination of HARDWARE & SOFTWARE)
Press 0, to listen to the Premaster Sample (The Mix down with nothing on the master bus)
**Feel free to try out your own favourite compressors and add to this list!!!
Here is the link to download the audio files / samples separately:
ZIP file Password: zeitgeist
Included, you will find 6 different genre WAV samples, each with a:
*MILD processing through each compressor (around 1 to 1.5 dB reduction)
*MED processing through each hardware compressor (around 1.5 to 3 dB reduction)
*Normalised Audio File (@ 0 dB FS – good for comparing to the master & processed files)
*Premaster Audio file (file prepared for mastering – lower in level)
*Mastered file done by us @ Zeitgeist Audio Mastering, Berlin (http://www.zeitgeistmastering.com/)
We’d like to specially thank Following Artists for the Songs have been used for the AUDIO SAMPLES:

Using some new software, I try my best to imitate various Dota 2 voices like Enigma, Drow, Elder Titan, and more. It was quite a hoot. Did you like my Indian JimBen impression?
Made Possible by: http://www.audio4fun.com/voice-over.htm
AV Voice Changer Software Diamond is designed to capture and modify your voice to create a wide variety of different new voices. It also has a comparator feature which lets you import someone’s voice as a .wave file for the program to automatically mimic your voice to. You can also add effects, imitate object sounds, and work with various projects all within the software.
Because I believe in transparency, this is a paid endorsement, but I genuinely enjoyed working with the product and working with them has been nothing but professional and pleasant.
New videos every Mon/Wed/Fri + weekly live streams!
OBS (Open Broadcast Software) – Week 4 covering several methods of getting your audio into an OBS mix – including an HOA or AV coming in via a capture card from another computer!
This is the fourth of a series of tech shows I’ll be presenting weekly. The software being discussed on this show is available at http://obsproject.com and is open source and free. It allows professional switching and composing of scenes with cameras and screen shares together that you can stream into YouTube Live Events among other streaming sites.
This week, we’ll discuss methods to get audio from an HOA or “Hangout-On-Air” into the show you are hosting, so they hear both your local microphone AND the participants in the HOA. (Actually, it could be an HVC or “Hangout Video Call” just as easily, but it is not a bad idea to have the HOA as a backup show in case the Live Event had problems and doesn’t record or stream optimally.)
This additional video shows how to use Voicemeeter to get audio into OBS (basic) https://www.youtube.com/watch?v=iPh2_5m0cGA
And this one shows how to record a Skype call into a show where they can hear you but they do not hear their own voice echoed back at them:
Thanks especially to +Dan McDermott, the original inspiration behind these techniques, and to +Michael Mason and +Hosted Hangouts for pushing the envelope even further. Dan and Michael are truly producers-extraordinaire exploring the possibilities of these hybrid types of programs.
Next week and the following one we’ll be moving on to talking about Pixlr.com’s incredible editor and some things you can do with that.
