When it comes to choosing the best audio format for video and, despite that there are more audio codecs, we always come to the same comparison between WAV and MP3.
Geeks will tell you that the WAV format has better audio quality (really has it). But, on the other hand, practical people will say that there’s no difference (although there is) and is smaller.
So, we can define this debate as an endless struggle between audio quality and file size.
But, in summary:
- WAV has much better quality, but files are huge. Lower compatibility in general.
- MP3 files are very little, but has a much lower quality. Higher compatibility in general.
So, there’s no definitive answer, especially nowadays. But, we think that the best option is simply which suits you best in terms of audio quality and file size.
To dive further in this WAV MP3 thing, we’ll talk about the main factors that define the best option for any case. Thus, you’ll be able choose the audio format that you need.
The first thing to check is:
Audio Compression Ratio.
The audio compression ratio in digital audio formats, defines the amount of sound information per second. This means that the more information per second, the better the audio quality. However, it implies that the file is bigger.
This compression ratio is measured through something called “bit rate”. It’s defined by the amount of kilobits per second (Kbps). So,more kbps means higher audio quality but higher file size.
Every audio codec has its own compression ratio. Here’s a list with the most popular ones:
- MP3: 128 to 320 kbps
- WAV: 1,411 kbps
- FLAC: 1,411 kbps
- AAC: 264 kbps
Another essential aspect to keep in mind, is:
2. Audio Codec Compatibility
As you know, some types of files are more used than others. So, there’s always a “industry standard” that benefits the usage of specific codecs over others.
In this case, WAV and MP3 files are the most used in the industry by a series of factors. Mainly, their popularity is due to the fact that they are the ones who have been in the industry the longest. So, most of the platforms and gear are made to support these formats over than others.
Therefore, it is difficult to imagine using an audio codec for video other than MP3, simply because it is the most popular and efficient.
Quality is not the only factor to revise when choosing an audio codec for your video. Compatibility is an essencial factor to define which one suits you best.
So, you are much more likely to find platforms that use MP3 rather than WAV. Just like Youtube, Social Media, etc.
Anyways, there’s always a new factor to define which codec suits you best, so we encourage you to compare them and tell us what you think.
But we want you to remember that:
- WAV has much better quality, but files are huge. Lower compatibility in general.
- MP3 files are very little, but has a much lower quality. Higher compatibility in general.
