Basic Audio Principals 101

By | December 6, 2007

This week’s episode was recorded last month on location in Aylmer, ONT CANADA. The audio quality of the interview is not superb because of a problem with my screencapture software, sorry. We go over audio basics and start talking about sound in general, frequencies, volume, decibels, all that technical talk. This is the beginning of a 1 hour session that introduces basic audio principals and we’ll apply that knowledge to recording podcasts. Later on, the training will include a kick-start to Audition 3.0, as well as some tips on using Audition.

    Hi Ken,

    I really like your podcast, but I have some questions.
    Why are you switching between diffrent types of file formats? Some are in Mp3, some in mp4 and some are in m4a.
    You are often refering to other pods later on when you having some problems, when are you producing those pods?
    This latest pod, the one that I’m commenting, seems not to be working. Tried to download it two times but I just get this error message: “Error -50: unknown error”.

    Keep up the good work and tnx for this excellent blog/pod.

    Jesper from Sweden.

    For awhile now I have been experimenting with different encoders and formats. The primary concern is compatibility with iTunes, and secondly I’m trying to get a resonable file size. Of course, it also depends on if the file is audio only, or if it is a screencast.

    Now aside from that, I will say that I’ve been having problems with my video encoder and I’ve gone through some different apps experimenting with them to see what produces the best results. As of late I’ve tried QuickTime Pro (which is terribly slow). I think something is botched on my sysem though (as far as QT is concerned) because I’m having problems viewing QT files online, some type of plugin error.

    I encoded this episode with MediaCoder which is an OpenSource encoder that allows for batches of video to be encoded. There appears, however, to be a problem with the settings there as well. I uploaded this file as a test to see if it would play on the web.

    I am re-encoding right now with an application that only lets me encode at 320×240 (formatted for the iPod) and I’ll reupload shortly.

    Long answer, I know, but its a very tricky topic. I think I’ll have to wipe my system out and start over to be sure its not an issue on my end.

    And one thing I forgot to mention, sometimes I play with an enhanced podcast, so that is another format that you’ll see! I encode those on my Mac in GarageBand. Maybe I should move all my encoding over there?

    Hi Ken – greeting from Hollywood, California!

    I just discovered your site – thanks for all the wonderful information. I’m hoping to launch my own blog first of 2008 and your site is a BIG help.
