Audio setups for recorders or sound interfaces can be very confusing. But, if you are going to work with videos or podcasts , it will be useful to know how to interpret the parameters when recording and exporting files, whether in Audacity (free), Reaper, Adobe Audition or in video editors . Here we are going to talk about the differences between sample rate , bit depth , file compression rates and format variations . Thus, you will be more sure of the options you have in relation to the audio quality and you will be able to guarantee good results. In short, you will understand why we recommend recording in uncompressed format ( WAV, for example) at 24 bits and 48 kHz . In addition, you whatsapp mobile number list will also know the reason why, in most cases, we do not need more than a 192 kbps MP3 to export excellent quality audio. We will also talk about the possibility of compressing more podcast files, which can be generated in 64 kbps MP3 , mono , to facilitate online consumption. Formats, extensions and codecs: What do they mean? When it comes to audio files, we can talk about formats, extensions and codecs. In short, we can say that the format refers to the type of file, identified by its extension ( *.mp3, *.wav, *.ogg, *.wma etc ), which often tells us how it has been encoded or which it's your codec. For example, a file in the MP3 format has a *.mp3 extension and MPEG-1 Audio Layer III codec . Examples of audio file extensions Normally those endings are mixed. But what is important to know is that, just like in videos, files with the same type of extension do not always have the same codec and vice versa . This information is valid so that you do not feel lost in case you do not understand the reason why a software, which normally plays your *.m4a files , does not play another one with the same extension, for example. Such a situation could indicate that the codecs used are different. In that case, the solution would be to use other software to read the file or to convert it (re-encoding). This can even be done in video editors. The variations of formats and codecs depend on the options of the companies that develop the software that executes the files. In these cases, many things are at stake, such as technical specifications and patent relationships.
