How to use a Compressor on your Podcast Audio

Using a compressor and limiter for your podcast

Audio compression can make any podcast sound better. There are two types of audio compression that we use on our podcast to make our audio sound like it does on the radio. On our digital audio mixer will use a basic compressor and limiter to make sure that our podcast voices do not peak. This allows us to limit how loud each microphone can be by reducing the dynamic range of the signal through compression. The second type of compression that we will use come from VST3 plug-ins on our computer. These plug-ins combine EQ, compression, limiting and gating all in one convenient interface to provide a complete audio mixing chain that will quickly deliver a clear, warm and open sound. The compression on a digital audio mixer simply helps us prevent peaking in the VST3 plug-ins take compression the rest of the way.

When you use the compression and limiter on your digital audio mixer you will have the ability to set a threshold for where you want the compressor to start. I generally recommend setting a high-level threshold of negative 1-5 dB for your compressor and limiter. Similar to the noise gate settings you will have the ability to set an attack and release to control how much time in milliseconds you would like the compressor to ramp up and down. Compressors work with a ratio that starts at 1:1 and goes to infinity. A ratio of infinity is complete silence. Compression will occur when the signal is above the threshold and the game will be reduced by the ratio set. For example a ratio of 4:1 means that when the input signal increases above the threshold by 4 dB the output signal is only increases by 1 dB. The higher the ratio, the more gain reduction occurs.

Now that our digital audio mixer is set up with the basic compressor let’s move on to understanding VST3 plugins and ASIO audio drivers in our next video.
