Uncompressed audio is generally considered better in terms of audio quality because it retains all the original data and details of the sound. However, compressed audio formats offer smaller file sizes, making them more convenient for storage and transmission in certain situations.
And now take a closer look
Uncompressed audio is generally considered better in terms of audio quality because it retains all the original data and details of the sound. However, compressed audio formats offer smaller file sizes, making them more convenient for storage and transmission in certain situations.
Audio compression involves reducing the file size of an audio recording by using various algorithms that remove redundant or unnecessary data. This process significantly reduces the file size, making it easier to store and transmit. On the other hand, uncompressed audio files are exact replicas of the original sound, preserving all the subtle nuances and details.
While compressed audio formats provide convenience, they do come with some drawbacks. One of the main issues is that compressed audio files lose some of the original audio data during the compression process, leading to a slight decrease in quality. This loss of data is often achieved by removing frequencies that are less audible or by using perceptual coding techniques.
The choice between compressed and uncompressed audio depends on the intended use and priorities of the audio. If audio fidelity is of utmost importance and storage space or bandwidth is not a concern, uncompressed formats such as WAV or FLAC are preferred. They are commonly used in professional audio production, mastering, and archiving.
On the other hand, compressed audio formats like MP3, AAC, or OGG are widely used for music streaming, portable music players, and online distribution platforms. These formats significantly reduce file sizes without compromising the listening experience for the majority of listeners. The trade-off between file size and quality is carefully balanced in order to provide acceptable audio quality at reduced bitrates.
In the words of Neil Young, musician and advocate for high-quality uncompressed audio, “In the world of digital music, you’re supposed to be able to hear everything, but there’s a price you pay for that, especially with the compression algorithms used by most people.” This quote underscores the trade-off between convenience and audio quality.
Interesting facts about compressed and uncompressed audio:
-
The MP3 audio format revolutionized the digital music industry when it was developed in the late 1980s. Its ability to significantly compress audio files without causing significant quality loss paved the way for widespread music sharing and online distribution.
-
Uncompressed audio formats require significantly more storage space compared to compressed formats. For example, a CD-quality uncompressed audio file can occupy around 10 MB per minute, while the equivalent MP3 file may only occupy around 1 MB per minute.
-
The development of lossless compression formats, such as FLAC (Free Lossless Audio Codec), bridged the gap between compressed and uncompressed audio. These formats offer the convenience of smaller file sizes while preserving all the original audio data.
Table comparing compressed and uncompressed audio:
| Aspect | Compressed Audio | Uncompressed Audio |
|---|---|---|
| Audio Quality | Moderate to High | High |
| File Size | Small | Large |
| Data Loss | Some loss of original audio data | No loss of original audio data |
| Applications | Music streaming, portable devices | Professional audio production, archiving |
| Common Formats | MP3, AAC, OGG | WAV, FLAC, AIFF |

In this video, Paul discusses the comparison between uncompressed and compressed audio files. While he acknowledges that uncompressed files have advantages such as lower strain on power supply and less noise generation, Paul emphasizes that streaming companies prefer compressed files for data usage and cost savings. For local storage, he recommends using uncompressed files like AIFF, which supports metadata. Furthermore, Paul mentions their upcoming server that uses galvanic isolation to completely isolate the digital signal from power supply noise, resulting in improved sound quality. Ultimately, he concludes that there is generally no need for uncompressed audio files unless streaming is a concern, as streaming will always be a part of the audio experience.
There are also other opinions
To the average listener, there isn’t much difference in the sound quality between high quality compressed and uncompressed formats. Unfortunately, every time an audio file is converted into a compressed format, it’s not a perfect copy and it loses information.
Uncompressed audio is audio without any compression applied to it. This includes audio recorded in PCM or WAV form. Lossless audio compression is where audio is compressed without losing any information or degrading the quality at all.
A uncompressed file format has a bigger file size and has better sound/video quality. A compressed file format has a smaller file size and has poor sound/video quality.
