Benchmark Audio Encoding Performance, How ?

[St Devious]

Need to benchmark audio performance of some PCs. How should I do it ?

needs to use multi- core CPUs

help here

foobar supports multicore systems and informs the time/speed.

LameXP offers multi-core support too. But no special benchmarking tools yet. It will tell you the total time it took for converting all files though :)

I have been using that till now. But I have been running into a peculiar problem. The first encode takes like 20s more than all the following encodes. This is with all the files ripped from CD to WAVs on disk. Then WAVs being encoded to MP3s.

ahaa. thanks.

I tried your software. It has interruption of some kind while changing the files it is encoding due to which the CPU usage is not 100% continuously.

HDD bottleneck, probably ;)

You aren't encoding from WMA, are you? Due to a bug in the WMA decoder, I enforce that never two instances of the WMA decoder run concurrently...

ya could be hdd.

not using wma tho.

[LoRd_MuldeR]

not using wma tho.

Then I assume you are bottleneck by HDD.

I found out the reason. The output folder was set on a different HDD. Now everything is good and it is pretty consistent. I'll be using it in my hardware reviews on my website in future.
