Waveform audio files also called WAV files are one of the more popular digital audio formats and a gold standard in studio recording.
WAV was one of the first digital audio formats , and quickly became a staple across all platforms. WAV files capture and recreate an original audio waveform at the highest quality without affecting or altering the sonic characteristics of the sound in any way. This provides enormous versatility allowing for superb editing and manipulation. Offering sample rate and bit depth options just like WAV files, AIFF registers the audio waveform as accurate samples slices using PCM to offer the highest possible audio recording quality and sound replication.
It mainly boils down to history. AIFF was created by Macintosh in , allowing full studio-quality audio recording and playback on Apple computers. With the boom of internet file-sharing in the mids, people quickly realized sending uncompressed files over dial-up connections was impractical—and oftentimes impossible.
With compression algorithms that were capable of achieving impressively small file sizes, MP3 became a staple of the internet era and has maintained its strong position to date.
However, small file size came at the cost of sound quality. Take the pair of images above. On the left, you can see every little wrinkle and color vividly. A highly compressed image on the right , however, becomes very pixelated and loses all of the clarity and detail. The same happens when you compress an audio file.
Different compression formats use varying methods to re-encode the data in a way that saves space. But this saving of space means some data has to get lost in the process. The lower the encoding quality, the more frequencies and details will get lost in your audio. So if you want to maintain good quality, yet still make use of the fact that MP3s are easy to share with friends and family, keep your bitrate above Kbps kilobits per second.
Often seen as the successor to the MP3, this Mac-centric compressed audio format found its true place with the birth of the iTunes Store, where it became the primary format for all music purchases made through the online music store. It is still the preferred format for all audio included in apps that are released on the Mac and iOS App Stores, as well as Nintendo and PlayStation products.
This results in smaller file sizes, all while delivering higher audio quality. When deciding which audio format is right for you, the first question you have to ask is whether the file needs to provide uncompressed audio or can it be in a compressed audio format?
Additionally, following the Red Book standard to provide for the ultimate listening experience, CD-quality audio should use uncompressed audio files at On the other hand, if your intent is to make sharing your music easy and fast, choose a compressed audio format that will provide you with small file size.
At that point, convenience will always win. Additionally, since email providers limit attachment sizes and smartphones have limited storage space, any audio format that can offer smaller file sizes is going to be a winner.
For all of those instances, choose a compressed audio format like MP3 or M4A. The smaller the file, the worse the audio quality will be. Well, that will really depend on your use case. For starters, the historical prevalence still stands today. The great news is, regardless of which of the two formats you choose, you will achieve exactly the same superb audio quality.
