STATIC MIXA MIX THAT REQUIRES NO VOLUME AUTOMATION…
STATIC MIXA MIX THAT REQUIRES NO VOLUME AUTOMATION…
BUT WHY DO WE USE VOLUME AUTOMATION..?
BUT WHY DO WE USE VOLUME AUTOMATION..?
TO MAINTAIN APPROPRIATE LEVEL FOR A CHANNEL IN OUR MIX WHEN;
BUT WHY DO WE USE VOLUME AUTOMATION..?
TO MAINTAIN APPROPRIATE LEVEL FOR A CHANNEL IN OUR MIX WHEN;
1. THE LEVEL OF A CHANNEL NEEDS TO INCREASE/DECREASE BECAUSE THE WAVE FORM REDUCES/INCREASES.
BUT WHY DO WE USE VOLUME AUTOMATION..?
TO MAINTAIN APPROPRIATE LEVEL FOR A CHANNEL IN OUR MIX WHEN;
1. THE LEVEL OF A CHANNEL NEEDS TO INCREASE/DECREASE BECAUSE THE WAVE FORM REDUCES/INCREASES.
2. THE LEVEL OF A CHANNEL NEEDS TO INCREASE/DECREASE BECAUSE THE LEVEL OF OTHER CHANNELS REDUCES/INCREASES.
BUT WHY DO WE USE VOLUME AUTOMATION..?
TO MAINTAIN APPROPRIATE LEVEL FOR A CHANNEL IN OUR MIX WHEN;
1. THE LEVEL OF A CHANNEL NEEDS TO INCREASE/DECREASE BECAUSE THE WAVE FORM REDUCES/INCREASES.
2. THE LEVEL OF A CHANNEL NEEDS TO INCREASE/DECREASE BECAUSE THE LEVEL OF OTHER CHANNELS REDUCES/INCREASES.
THE VARIATIONS IN THE VOLUME LEVEL OF AN AUDIO FILE IS KNOWN AS;
DYNAMIC RANGE
DYNAMIC RANGE
DYNAMIC RANGE
THE DIFFERENCE IN VOLUME BETWEEN THE QUIETEST & LOUDEST POINT
DYNAMIC RANGE
THE DIFFERENCE IN VOLUME BETWEEN THE QUIETEST & LOUDEST POINT
PROPERTIES OF AN AUDIO FILE
PROPERTIES OF AN AUDIO FILE- DYNAMIC RANGE
PROPERTIES OF AN AUDIO FILE- DYNAMIC RANGE- SIGNAL TO NOISE RATIO..?
PROPERTIES OF AN AUDIO FILE- DYNAMIC RANGE- SIGNAL TO NOISE RATIO..?
I QUITE LIKE THIS VIDEO.
Star Wars Geek Talks SNR (Signal To Noise Ratio)
WHY IS THE SNR IMPORTANT..?
WHY IS THE SNR IMPORTANT..?BECAUSE IF I HAVE A LOW SIGNAL TO NOISE RATIO AND I WANT TO INCREASE THE VOLUME OF THE AUDIO FILE..
WHY IS THE SNR IMPORTANT..?BECAUSE IF I HAVE A LOW SIGNAL TO NOISE RATIO AND I WANT TO INCREASE THE VOLUME OF THE AUDIO FILE..
THEN I INCREASE THE LEVEL OF ‘UNWANTED’ NOISE TOO.
WHY IS THE SNR IMPORTANT..?BECAUSE IF I HAVE A LOW SIGNAL TO NOISE RATIO AND I WANT TO INCREASE THE VOLUME OF THE AUDIO FILE..
THEN I INCREASE THE LEVEL OF ‘UNWANTED’ NOISE TOO.
I THEN FIND IT DIFFICULT TO GET ‘CLARITY’ IN MY MIX.
DBFS
DBFS- DECIBELS RELATIVE TO FULL SCALE
DBFS- DECIBELS RELATIVE TO FULL SCALE- ZERO DBFS IS THE MAXIMUM POSSIBLE DIGITAL SOUND
LEVEL WITHOUT CLIPPING/DISTORTION
DBFS- DECIBELS RELATIVE TO FULL SCALE- ZERO DBFS IS THE MAXIMUM POSSIBLE DIGITAL SOUND
LEVEL WITHOUT CLIPPING/DISTORTION- DIGITAL SOUND LEVELS ARE MEASURED IN TERMS OF HOW
FAR THEY ARE BELOW ZERO DBFS.
DBFS- DECIBELS RELATIVE TO FULL SCALE- ZERO DBFS IS THE MAXIMUM POSSIBLE DIGITAL SOUND
LEVEL WITHOUT CLIPPING/DISTORTION- DIGITAL SOUND LEVELS ARE MEASURED IN TERMS OF HOW
FAR THEY ARE BELOW ZERO DBFS.- YOU MAY HAVE NOTICED THIS IN LOGIC…
DBFS- DECIBELS RELATIVE TO FULL SCALE- ZERO DBFS IS THE MAXIMUM POSSIBLE DIGITAL SOUND
LEVEL WITHOUT CLIPPING/DISTORTION- DIGITAL SOUND LEVELS ARE MEASURED IN TERMS OF HOW
FAR THEY ARE BELOW ZERO DBFS.- YOU MAY HAVE NOTICED THIS IN LOGIC…- NO?
DBFS- DECIBELS RELATIVE TO FULL SCALE- ZERO DBFS IS THE MAXIMUM POSSIBLE DIGITAL SOUND
LEVEL WITHOUT CLIPPING/DISTORTION- DIGITAL SOUND LEVELS ARE MEASURED IN TERMS OF HOW
FAR THEY ARE BELOW ZERO DBFS.- YOU MAY HAVE NOTICED THIS IN LOGIC…- NO?- OBSERVE THE PEAK LEVEL INDICATORS.
A GUIDE TO RECORDING LEVELS
HEADROOM- THE DIFFERENCE BETWEEN THE PEAK LEVEL ON YOUR
STEREO OUTPUT (MIX BUS) AND ZERO DBFS
HEADROOM- THE DIFFERENCE BETWEEN THE PEAK LEVEL ON YOUR
STEREO OUTPUT (MIX BUS) AND ZERO DBFS- THE RESULT OF ADDING A NEW CHANNEL TO YOUR
RECORDING WILL INCREASE THE OVERALL LEVEL OF YOUR OUTPUT
HEADROOM- THE DIFFERENCE BETWEEN THE PEAK LEVEL ON YOUR
STEREO OUTPUT (MIX BUS) AND ZERO DBFS- THE RESULT OF ADDING A NEW CHANNEL TO YOUR
RECORDING WILL INCREASE THE OVERALL LEVEL OF YOUR OUTPUT
- YOU NEED TO MANAGE YOUR MIX SO THAT AS YOU ADD CHANNELS YOU RETAIN ‘HEADROOM’ IN YOUR MIX.

- YOU NEED TO MANAGE YOUR MIX SO THAT AS YOU ADD CHANNELS YOU RETAIN ‘HEADROOM’ IN YOUR MIX.
- OTHERWISE EVEN THOUGH INDIVIDUAL CHANNELS MAY ALL BE COMFORTABLE BELOW ZERO DBFS YOUR MIX BUS MAY BE CLIPPING.
