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.

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

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.

- OTHERWISE EVEN THOUGH INDIVIDUAL CHANNELS MAY ALL BE COMFORTABLE BELOW ZERO DBFS YOUR MIX BUS MAY BE CLIPPING.
