It’s always possible to convert uncompressed files into a new format. It’s entirely possible that commercial audio hardware in the next decade or so will be able to express bitrates greater than 160Kbps, so keep your old uncompressed files. Future audio formats could require greater bitrates, and future connections or hardware could potentially deliver high-fidelity audio. Regardless, if you’re creating audio of any kind you should always keep your highest-quality files around to future-proof against new technology. Variable bit rate can become useful when looking at the amount of details needed, as it continuously changes bit rate throughout playback. When producing audio, you need to keep in mind how your listener will be interacting with your audio. When you’re starting a new audio project, it’s good to record the best quality you possibly can, with a high sample rate and bit depth. Most earbuds, and many desktop speakers, will not be able to express those frequencies. CD-quality bitrate, which is high, sounds its best on a professional stereo system that is able to adequately express the very high and very low frequencies 1,411Kbps is able to accommodate. If users are listening to your audio on mass-market earbuds or headphones, they will not be able to get everything that high-fidelity audio offers anyway. However, below about 90Kbps the human ear will notice a significant drop in quality, even without training.Īlso, a high-bitrate and high-fidelity file does not matter if it’s not delivered on quality hardware. If they’re streaming it, you likely want the bitrate to be a bit lower so it can be streamed effectively. If listeners will be downloading it or listening to it on physical audio formats, you can afford a high bitrate. Keep in mind how your digital audio is going to have to contend with bottlenecks. High bitrates appeal to audiophiles, but they are not always better. The MP3 format can range from around 96 to 320Kbps, and streaming services like Spotify range from around 96 to 160Kbps. More information, in a very general sense, means better sound quality.Īudio CD bitrate is always 1,411 kilobits per second (Kbps). In general, a high bitrate means high-quality audio, provided the sample rate and bit depth are also high. The right bitrate for a file depends on what you want to use that file for and the means of delivering the audio.
