MP3 Sound Quality & Organizing a Digital Music Library

December 7th, 2005 · 3 Comments

The MP3 format celebrates its 10th birthday this year (it was actually invented a couple of years before that but 1995 was its first real public appearance with available software players…those interested in the history of the MP3 should read the wikipedia entry) and it continues to be the most widely used digital music format. Many people would agree that it offers the best compromise between file size and audio fidelity with the widest range of hardware and software support. Sure, other formats such as WMA and Ogg Vorbis have gained footholds and offer arguably better sound and compression (especially at low bitrates) but they aren’t as widely supported.

As this article in Wired points out, as storage space has increased in capacity and decreased in cost, and improvements have been made in hardware and software used for digital music playback, some folks are listening to their 128 kilobits per second music libraries and finding themselves dissatisfied with the quality of sound. This Wired points out the LAME MP3 encoder which is an opensource project that strives for the best possible sound quality of MP3s.

I’ve been using the LAME encoder for a couple of years as my primary encoding tool with dbPowerAmp and it sounds much better than the iTunes MP3 encoder (especially north of 192kpbs which is the sonic compromise I’m willing to live with for portable digital music). LAME is easy to use and comes highly recommended to those who don’t mind the extra step of using an encoder and then importing the files into iTunes.

From my perspective, at the rate that hard drive prices continue to drop and digital music hardware/software continues to improve, any lossy compression scheme will eventually fall short. I’m starting to encode everything using the lossless FLAC format and then using software like Anapod to transcode into a lossy format when I want to fill my iPod. For some music, I’ll leave it in FLAC format and use my iAudio X5 (which other than the Rio Karma is the only portable digital music player that supports FLAC) when I really want to hear something with full dynamic range.

Whether LAME MP3 or FLAC, I am slowly but surely moving to encode my collection to digital and store it on a series of external hard drives…this is much more to my liking than CDs (and takes up far less space). I’m still experimenting with directory structures and naming schemes, and have yet to find a music library manager that does a thorough job accounting for the music from both commercially produced CDs and live CDs (my Grateful Dead and Phish collections alone are well over a terabyte). Some music library managers tap Gracenote or freedb to help populate tracklists and album credits, and others have taken to grabbing that information from Amazon.com. Ideally, the perfect solution would be a music library manager that grabbed info from all of those sources, as well as the All Music Guide and also tapped the incredible live music database at etree.org for unreleased live material. The icing on the cake would be that this software would also integrate with iTunes for playback and syncronize with iPods and other portable devices, transcoding on-the-fly as necessary. And a good universal tagging/renaming engine is a must.

Does anyone out there know of any software that comes close to this functionality?

    Stressed by compressed media files

    If you’re like most digital music users, you’ve probably done a double take when listening to certain songs in your collection that sound a bit strange. Maybe it’s a general tinnyness, or a cymbal that seems too sharp, or complex arrangements that a…

    […] Wired continues their series on digital music formats with A Music File by Any Other Name, an article comparing the most common lossy formats, and discussing which ones are the most future proof. As I mentioned in yesterday’s posting, the only truly future proof way to store digital audio is to use a lossless codec like FLAC, Shorten or Apple Lossless Codec and convert to compressed lossy formats as needed. Hard drive space is getting cheaper and cheaper…I’ve gotten no fewer than 3 emails this week alone from places like buy.com offering external 320 gig hard drives for about $170….so at about 50 cents per gig and considering you can store about 3 albums per gig in FLAC format it seems pretty economical if you want the maximum quality possible. Wired plans to cover lossless formats in a future article. Wired has gotten a lot of feedback on their music articles published this week and opinions vary widely…take a look here to see what readers have to say. […]

    Tiger Direct is selling 300 gig internal drives RIGHT NOW for $89. Outpost.com is selling them for the same price (with rebates involved.) You can easily get 300 GB of storage for $100, and next year at this time it is likely that that number will be 500GB.
