ffmpeg

Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:

*The gate resistor: a bit of theory*

When cruyising the internet for Triac switches, you may have come across a large diversion 
in the value of the gate resistor value. My choice usually is to take the lowest value that 
will still protect the gate and the optocoupler. Reader Mali Lagunas did some research in 
the theory behind the criteria to choose the value of the gate resistor. 
Which i will copy below:

The resistor when placed in this circuit, will have two main effects:
a) It will limit/provide the current going into the gate of the triac (I_{GT})
