But jeeze, disk is cheap these days, so why bother chasing smaller files? Computer disk space is cheap, but not so in tablets and smart phones. In those devices, there is a hard limit, which cannot be expanded (many devices no longer have SD card slots. My phone is 16 GB and tablet 32, IIRC. at the moment, my music collection is about 3 GB.
Well, with either IOS or Android, you don't HAVE to have all your music on the device. (Unless you are trapped in a stingy data plan).
I like to have the same collection on both my phone and tablet. I also have some mp3s on a USB stick, which I can plug into my receiver. However, the reason for this question is the app I have on my tablet that allows me to play mp3s from my collection to the Yamaha receiver. However, it ignores ogg. I could redo all the CDs I have in ogg, but that would be a lot of work, though I suspect not as much work as trying to get Yamaha to support ogg. ;-)
Anyway, Jeff Attwood did a often cited Bitrate Experiment, whic gives clues for encoding: http://blog.codinghorror.com/the-great-mp3-bitrate-experiment/
Generally, I agree with him and have no use for the "golden ear" audiophiles, who typically have more money than brains. However, I have noticed, on some recordings, artifacts of the compression. I suspect a higher bit rate might reduce that, but can't be sure. Incidentally, I have been working with digital audio, going back 40 years, with PCM voice channels in telecom. About 30 years ago or so, compression was sometimes used, first with ADPCM and later the various G. codecs. Now, call quality is improving with HD voice. There are even some codecs that provide "broadcast" quality audio. https://en.wikipedia.org/wiki/Wideband_audio Also, I have a friend who insists vinyl provides better quality than CDs. ;-) He apparently doesn't understand things like dynamic range, frequency response etc. Or perhaps he gets a warm feeling from surface noise. :-) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
