It’s off on the right decision to keep the sample type the same as the source audio material. The higher the rate of sampling, the greater fidelity the digital file will have to the actual acoustic audio waves.Ĥ4.1 kilohertz is the industry standard for CD recording while 88.2 kilohertz is considered the standard for premium, high-end audio.Īnything above that can be difficult for consumer technology to handle and is typically reserved for extremely slowed-down audio clips and high-frequency recording. The sample rate is the rate at which a digital sample is taken of an audio signal measured in kilohertz. Lower bitrates will save you storage space, but you will sacrifice dynamic range for that lower file size. ![]() It represents the total range between the lowest sounds humans can perceive and the highest sounds humans can perceive.Ī high bitrate means a larger file size, but a greater dynamic range. The more storage space you dedicate to the audio file, the greater its dynamic range is going to be.ĭynamic range in audio is essentially the same as dynamic range in photography and videography. Bitrateīitrate, also known as bit depth, represents the amount of storage space that you’re dedicating to this audio file. I’m going to take a second to unpack terms like bit rate, sampling, and a few other tips that you should know for working with the MP3 file type. I used a lot of audio production terms walking you through the step by step of how to create an MP3 using Adobe Audition. Tips for Exporting Adobe Audition Files to MP3 How to remove background noise with Audition. ![]() Now that you’ve got a good understanding of what makes MP3 so popular, let’s create one! You can send a quick MP3 cut of vocals to your producer or bandmates to get a feel for things before you export to something without the lossy compression. MP3 is also a great option for sending a test recording before you bother with the final project. I’m regularly exporting projects to MP3 as some websites, like Patreon, still prefer the smaller file size over higher-end options. MP3 is still prized for its balance of quality and small file size. The MP3 algorithm compresses the highs and the lows of an audio recording which most listeners can not normally hear anyway. The term “lossy” simply means that the compression cannot be reversed and parts of the original audio recording are lost permanently during the compression. MP3 files work by using a lossy compression algorithm. The same 3-minute song on an MP3 file is about 90% smaller than that same song on a WAV file. To give this conversation some perspective. There was a strong demand for a file type that could retain high audio quality but also come in a package that was small enough to easily transfer over dial-up internet. This was a period of time when the internet was rapidly expanding and file storage was much harder to come by. The MP3 encoding was first developed in the late 1990s. I’ll spare you the technical jargon and get right to what made MP3 so popular. It’s a coding format for digitized audio recordings. MP3, also spelled mp3, is formally known as MPEG-1 Audio Layer III. ![]()
