If, however, I am doing audio that will go into a video file–which I do for my video podcast–and I know that the MP3 will get re-encoded later with the video, then I will choose a higher sound quality. Much higher than that and you won’t be able to tell a quality difference in the spoken audio. You can probably go a bit lower before you start to hear sound quality issues. This gives the largest file size for compatible settings of the various options, but also gives me more confidence in the compatibility of the final file.įor a podcast that is is just spoken word with no music, I usually choose 96 kbps. I always choose Constant (also called CBR in some editing software) on this option regardless of the project I am working on. The different bit rate options can give you smaller file sizes, but at the cost of potential compatibility and quality issues. (Lots of good data, in english (not geek) here, read all the way through this site) Only on expensive playback systems can most people tell the difference between 192Kbps and CD quality. 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. Using VBR allows the MP3 encoder to use lower bit rates during quieter or less complex parts of a song, and significantly higher bit rates during more complex sections. One final consideration should be to encode MP3s using a ‘variable bit rate’ instead of a ‘constant bit rate’. The difference in quality between 128kbps and 256kbps is vast and immediately obvious - your favourite tunes encoded at 256kbps will sound stunning in comparison to the same tracks encoded at 128kbps. This offers vastly superior sound quality over 128kbps, without eating up too much disk space. The happy medium between small file sizes and true CD quality audio is a 256kbps bit rate.
