For ultimate MP3 quality, you could choose 320Kbps, but so few people can hear the difference between this and 256Kbps (or real CDs, for that matter) that it's generally a waste of disk space. Only on expensive playback systems can most people tell the difference between 192Kbps and CD quality.įurther up the scale, if you want some compression but minimal degradation in sound, 256Kbps is a good compromise compared with CD audio, since the frequency response is generally identical to the original up to about 18kHz, and the difference between the two is barely discernible by most people, even on high-end systems. If you're looking for the best compromise for your MP3 files between compression ratio and audio quality, bit-rates of 160Kbps or 192Kbps are generally recommended, with 192Kbps, in particular - often being classed as 'near CD' quality - suitable for complex music or tracks with lots of bass content. However, when listening on a hi-fi or on studio playback gear, many musicians find 128Kbps difficult to listen to, especially since the frequency response falls off rapidly above 16kHz, high‑frequency sounds such as cymbals sound distinctly harsh, and you can often hear a low-level background 'warbling' sound, which is the main reason that some people dislike this rate. Solo acoustic music performances could be acceptable at 48Kbps, although 64Kbps is probably more in line with AM radio quality.įor reasonable-quality ensemble music, many people consider 128Kbps a good baseline, especially if the intended destination is computer speakers or in-car audio systems. Spoken word is still perfectly intelligible down to about 24Kbps, which is usually perfectly sufficient for podcasts, talk radio, and so on. MP3 files can be created at CBR (Constant Bit Rate) values from 8Kbps to 320Kbps. As long as you leave a few dB of headroom to give your MP3 encoder some 'space' to perform a clean result, the main decision to be made with MP3s is the target bit-rate. SOS contributor Martin Walker replies: I doubt that you'll hear any difference in practice by increasing the bit depth from 16 to 24. Will my method have a higher-quality outcome than 16-bit WAVs converted to MP3?Via SOS web site Can you explain a few things about creating MP3s? I'm currently converting WAVs to 24-bit, 44.1kHz and then converting them to MP3, but I'm not entirely sure what effect this kind of conversion has on the sound.
