Tool for Testing Bitrate Range
Hi, I've been lurking for awhile and abi has answered a few questions for me that really needed answering in the last few weeks. Thanks.
I have very specific needs and I am amazed at how hard it can be to find out relatively simple things, like what bitrates a given player supports. A few years ago I bought a Sony MP3 player and after I bought it I had to email them to ask what bitrates it supported and even though they already had my money they pretty much told me to shut up and play 128 kbit files on it. Since my major uses are audiobooks and occasionally OTR, their answer was unacceptable.
I created a group of files that may be burnt to a CD or copied to a microSD card and used to test MP3 players. You may pop the card in in the showroom and cut right through all the bull before you buy.
What you get:
68 files ripped 68 different ways from 8 kbit mono to 320 kbit stereo (LAME). The files have meaningful filenames and the audio content of each file is just my voice stating the bitrate and MP3 mode that the file was encoded in. You just load the files into the machine in question, hit play and let the player tell you exactly what it can do.
Download the ZIP file HERE. (~8.6 mb)
Download the ISO file HERE. (~9.2 mb)
It's a work in progress. I'd like to add some low bitrate VBR mono files but I haven't gotten around to it yet.
I just bought a Sansa c240, ran the test on it and was amazed that it outperformed the specs for the player. The specs state that it will play 32-320 kbits -- actually, mine plays 8-320 kbits flawlessly. Why they want to keep this a secret is beyond me. If people would test and post the results for their different players it would be a really great resource for folks who need players capable of playing a variety of low bitrate files like audiobooks, podcasts and OTR.
Anyway, have at it and thanks for the info I've gotten here. Don't be sidetracked by the audio quality -- the files are only about finding out what modes your player will really play.
