![]() There's a bit of debate over what "headroom" actually means as it's not a standard term. The AUDynamicsProcessor allows you to do this with one filter instead of two, which is a much more efficient use of system resources.Īttack time refers to the amount of time it takes for the compressor to implement a change in volume, and release time is the time taken to reduce the compressor back to its original level afterwards. So you apply an expander to lower the volume of the triangle to an acceptable level. The drums are now a lot quieter but you've noticed that the subtlety of the triangle has been lost - it is now far too prominent. The drums are far too loud so you apply a compressor to bring them down. Imagine some music where you have loud crashing drums, a relatively quiet triangle and a trumpet somewhere in between. The expander will then take the quieter sounds and reduce their volume (again, proportionally), thus evening out the amplitude variation of the quieter sounds and increasing the dynamic range. louder sounds will be reduced by a much larger amount), helping to even out amplitude variations. The compressor will reduce the louder portions of the audio in proportion to their distance from the threshold (i.e. Using a compressor and expander at the same time allows you to avoid overly-loud peaks while still maintaining dynamic range. Expansion lowers the volume when it is lower than the threshold (thus making quiet sounds quieter and therefore increasing dynamic range). Compression lowers the volume when it exceeds a certain threshold (making loud sounds quieter and therefore decreasing dynamic range). This filter allows you to adjust the dynamic range of the audio (the difference between the loudest and softest sounds). You could use the bandpass filter to isolate the center frequencies With rumbling traffic and high-pitched TV static in the background, Range of frequencies to pass through and rejects any frequencies ![]() Today I'll be giving details on the Audio Units with the FCP-specific Apple Audio Units (AU) which ship with the operating systemĪnd are available to any application, and FCP-specific ones. What Final Cut Pro offers out of the box.įilters in FCP are split into two categories ![]() This inspired me to create this guide to show people exactly Graphics, etc, but only knew a few ways of improving bad audio. They could handle editing, color correction, ![]() In my conversations with other editors it becameĬlear that for a lot of them (myself included), audio was a majorĪrea of weakness. ![]()
