wavegain for normalizing

Useful for people who want all the songs in their self-mastered album to sound similar in volume:
http://www.rarewares.org/others.php#wavegain

Simple commandline utility with a GUI frontend that creates batch files for use with the utility. Drawback is that it does not do what I do with SoundForge - normalize to arbitrary RMS values applying limiter/compressor transparently. It does have a -6 dB limiter option, but the way it works seems to be very different from what I'm used to - a much softer limiter, perhaps...

Tata photon backup network device for live audio stream

Plugging in the Tata photon to USB on the Mac in mandir causes problems with the USB midi device and so on. But connecting the tata photon to the USB port before booting, and leaving it connected to the USB throughout, is troublefree.

When I tried to switch back from Photon to LAN, BUTT did not reconnect. Also, I had to disconnect the LAN cable for the Photon to connect. So, if LAN does not work, the way out would be to use Photon till the end.

icecast bandwidth under-reported by awstats

Looks like the icecast bandwidth is under-reported by awstats.

Shoutstats is quite accurate, since it reports the number of connected listeners at any point of time.

Checking out the area under the curve as seen right now, even though yesterday was Sunday and shows less traffic as is usual on Sundays,


If we take the 1 hour units, we have the approximate numbers as the following list from left to right:

300
300
300
300
300
300

400
500
400
400
350
300

300
250
250
200
250
250

250
300
350
550
650
400

That comes to 8150 listener hours. Since our 1 hour of 24 kbps stream filesize is 10.8 MB, taking 11 MB per hour, this comes to 87.5 GB per day on a slow day. The numbers reported by awstat seem to be around half of this.
