Lame MT MP3 Encoding Test
In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which is a popular scenario that many end users work with on a day-to-day basis to provide portability and storage of their digital audio content. LAME is an open-source mid to high bit-rate and VBR (variable bit rate) MP3 audio encoder that is used widely around the world in a multitude of third party applications as a core audio encoding engine.
In this test, we created our own 223MB WAV file (a hallucinogenically-induced Grateful Dead jam) and converted it to the MP3 format using the multi-thread capable LAME MT application in single and multi-thread modes. Processing times are recorded below, listed in seconds. Once again, shorter times equate to better performance.
Here the Dell Studio Hybrid shows that its newer, more advance Core 2 Duo T5850 mobile chip, though its clock speed is nearly 300MHz slower, offers a bit more performance than the AMD Athlon 64 X2 dual-core desktop processor. In fact, the Hybrid even offers competitive performance to the Core 2 Duo E6600 full sized desktop test system. When it comes to audio encoding, processor horsepower is the gating item and the Hybrid has more than enough for this everyday task.
