These extensions get mixed up, but the important thing to know is that, just like videos, files with the same type of extension don’t always have the same codec and vice versa. ), which usually tells us how the file was encoded, or its codec.įor example, a file in MP3 format has a *.mp3 extension and MPEG-1 Audio Layer III codec. In a simple explanation, format is merely the type of file, identified in its extension ( *.mp3, *.wav, *.ogg, *.wma, etc. When referring to audio files we use terms such as formats, extensions and codecs. Formats, extensions, and codecs: What do they mean? We’ll also talk about the possibility of higher compression to podcast files, which can be created in mono MP3 format with 64 kbps, facilitating online access. In addition, you’ll also know why in most cases we won’t need more than an MP3 format with 192 kbps to export audio with excellent quality. In short, you’ll understand why we recommend recording in an uncompressed format ( WAV, for example) at 24 bits and 48 kHz. Thus, you’ll be more confident about your choices regarding audio quality and ensure good results. In this article, we’re going to talk about the differences between sample rates, bit depth, file compression rates and format variations. But if you’re going to work with videos or podcasts, you better know how to interpret these parameters when recording or exporting files, whether on Audacity (free), Reaper, Adobe Audition or even on video editors. ![]() Audio quality for recorders or interfaces can be quite confusing.
