Audio questions

2004-11-10 16:37:15.660446+00 by Dan Lyke 3 comments

After Mark's audio wrap-up of Bloggercon, I sat down to do my own, but... I'm only getting 11dB of signal on the Windows box, not enough to get comfortably out of background noise, and on the Linux machines I'm getting pops that sound like clipping, but not quite, no matter what my gain settings. I've tried two mics, a cheap $8 karaoke mike and a borrowed much more expensive beast, with the same results. Anyone know what's going on?

I am pretty sure the clicking pops are a sampling/encoding/decoding error. For example on some .mp3 files I hear them using XMMS and not MPG123, and sometimes the other way around. Typically when the sampling rate is lower (like for voice recordings).

Personally, still not sure where the draw for audio-blogging is.. just the lyrics from a song:

Everyone wants to be a Dee Jay.. My Mom wants to be a Deee.. Jay.. My Dog wants to be a Dee Jay.. make sense to me.

Among other things, they're intended for PC mics, which are electret and require the sound card to feed them power.

Take your expensive mic (hopefully a Shure 58 or an EV RE-20 or the like), and feed it into some sort of pre-amp, then feed the *line* in on your sound card.

That should set you up.

Well, the expensive mic was borrowed, so that's not a long-term solution. And it wasn't a super expensive mic, just a mid-range Sony.

I think I've got a system which is at least giving me intelligible audio, I'm going to try this audio blogging thing with the $8 karaoke mic for something I'm not sure I want search engines to find and see if I throw up my hands in disgust or not.
