With extra time in class, I decided to try another audio replacement project. You may have seen my last post ‘Film Sound Design – Sound for Intensity’ where I replaced sound effects from a movie clip. This time, I tried a little ADR.
Film Before Visual ADR
As you can hear, there is a lot of background noise that needs to be taken care of.
Film After Visual ADR
Coming Soon! Having issues with a copyright claim…
I synced up the video with the audio and cut the best one out to upload.
Screenshot coming soon!
Audio ADR Preparation
For this project, since the line is short and the actor recited the dialogue well the first time, we used audio ADR. The actor listened to the original audio looped and repeat with it for clear sound that could be synced with the video. This made some pretty good audio takes to use because after the actor repeats the line in a loop, it becomes more of a rhythm than a reading of the line; making it relatively the same as the original.
ADR Terms and Notes
Automated Dialogue Replacement (ADR) – Rerecorded audio to replace the audio of the video.
- Fixes technical problems
- Replaces vocal performance
- Makes a TV safe cut
- Creative purposes
- Usually recorded with large diaphragm condenser microphone
Post-Synchronization – Dubbing the sound over a video after it has been made; used a lot for dubbing.
Partial ADR – Must be recorded with the same mic, mic placement, and environmental reverb so that when clips are edited into the video it doesn’t sound off with the video sound. Not recomended.
Visual ADR – Having an actor watch the muted video and record the lines while watching it. Better for if you want to change the performance slightly.
Audio ADR – Having the actor listen to the lines and repeat with it while recording. Better for exact audio video fits.
Audio Post-production Terms
Equalizer – A tool that boosts or cuts the amplitude of specific frequency of specific frequencies.
High Shelf – The boosted area in a clip of sound that an equalizer has been used on.
Low Shelf – The area in a clip that an equalizer has cut the amplitude.
High Pass – Lets all the sound below a certain frequency be audible and cuts everything else.
Low Pass – Lets all the sound above a certain frequency be audible and cuts everything else.
Combing Effect – When the audio is duplicated and played up to 15 milliseconds after the normal audio, giving the audio a comb effect.
Delay Effect – When the audio is duplicated and played from 15-30 milliseconds after the main audio to present a chorus effect.
Echo Effect – When the audio is duplicated and played more that 35 milliseconds after the original audio to present an echo effect.
Reverb Effect – Like the echo effect, but instead adding varying pitches and more duplicates at different delayed times to present more of an effect of random and decaying echoes.
Chipmunk Effect – When audio is recorded at half the speed and played back at twice the speed to raise the pitch by an octave.
What I Learned and Problems I Solved
One things I learned was that YouTube editor doesn’t like me very much. After a little while trying to edit the video in YouTube editor, I ran into the same problem I kept running into several posts ago; copyright claims that don’t exist. However, I did learn a lot more terms and techniques used in ADR which will help me as I always want to use it to make my audio better. I also got more practice in editing and post-synchronization. Overall, this project was short but rewarding.
