Signal Repair

For most our tracks in the ep, we had used different ways of repairing audio in our tracks to make them more coherent and clean any potential problems when mixing or mastering. Crossfades were mainly a technique we used to merge small succession of audio and even merge long audio clips that were inherently very noisy such as foley or low level guitar picks.

An example of this is the car door beeps that we had to quantise to be used as intro for our track sleepy. To match it up with the tempo of the song we had to individually cut every track at its transients and lock them to every beat of the grid whilst applying cross fades to avoid pops and clicks with signal polarity mismatches.

We had also used a varying degree of signal repairing on some dialogues that we had recorded for our CIU project. In this we used basic dynamic processing techniques such as a de-esser and a de-breather.We shaved the HF by -11.5dBFS around 2.8kHz. We originally set the threshold at 5kHz since it was enough to clean the sibilances but 2.8kHz made sure to clean any potential problems since we had a lot of assets to fix. We used a low-cut filter to remove all the low frequency breath noises to clean the audio furthermore.
