How much compression do I need for voice over?
If the release is too slow then your quieter phonetics will also get compressed, which will make the voice over sound over-processed. around 10-20ms is usually a good ball park to aim for.
What is a good compression threshold?
Settings between 1.5:1 and 10:1 are the most common. A lower first number in your ratio will give you gentle compression you might apply to an entire mix, while a higher first number will give you an intense squashing effect.
How much compression should you use?
A compression test reveals the condition of your engine’s valves, its valve seats, and piston rings and whether these parts are wearing evenly. Healthy engines should have compression over 100 psi per cylinder, with no more than 10 percent variation between the highest and lowest readings.
What is a good compression ratio for vocals?
A good starting point for a rock vocal would be a 4:1 ratio with a medium-fast attack and a medium release. Then, set the threshold for around 4 to 6dB of gain reduction. Increase or decrease the attack time until you get the right level of forwardness for the mix.
What is a good EQ setting for vocals?
Best EQ Settings for Vocals
- Roll off the low-end starting around 90 Hz.
- Reduce the mud around 250 Hz.
- Add a high shelf around 9 kHz & a high roll off around 18 kHz.
- Add a presence boost around 5 kHz.
- Boost the core around 1 kHz to 2 kHz.
- Reduce sibilance around 5 kHz to 8 kHz.
What comes first EQ or compression?
Each position, EQ pre (before) or EQ post (after) compression produces a distinctly different sound, a different tonal quality, and coloration. As a rule, using EQ in front of your compressor produces a warmer, rounder tone, while using EQ after your compressor produces a cleaner, clearer sound.
What does too much compression sound like?
When you compress too hard with fast attack times, the dynamic range of your mix is squashed. You’ll end up with something that sounds like this: A song with no room to breathe; as flat as a pancake.
What goes first EQ or crossover?
EQs and other devices should always be in Line before the actual Crossover. Most DSP Units offer Input EQ which is essiantially that.
Where can I find a review of speech compression?
A highly readable and comprehensive review of speech coders can be found in “Speech Compression,” by J.D. Gibson [285] which appeared in Information. 2. For information about various aspects of speech processing, Voice and Speech Processing, by T. Parsons [141], is a very readable source.
Which is the best speech compression codec for Windows?
Assuming your users will be running Windows, there is a WMA speech compression codec that you can use with the Windows Media Encoder SDK. Failing that, you can use ACM to use something like G723/G728, ADPCM, mu-law or a-law, some of which are installed as standard on Windows XP & above. These can be packaged inside WAV files.
What kind of Technology is used for audio compression?
Speech and audio compression has advanced rapidly in recent years spurred on by cost-effective digital technology and diverse commercial applications. Recent activity in speech compression is dominated by research and development of a family of techniques commonly described as code-excited linear prediction (CELP) coding.
When was speech compression motivated by speech compression?
Motivated by speech compression, in 1976 Croisier, Esteban, and Galand [189] introduced an invertible filter bank, which decomposes a discrete signal f [ n] into two signals of half its size using a filtering and subsampling procedure.
