Yes, lossy compression can negatively affect sound quality by selectively discarding some audio data during the compression process. This results in a reduction in sound fidelity compared to lossless compression methods.
An expanded response to your question
Lossy compression can indeed have a significant impact on sound quality due to the intentional removal of certain audio data during the compression process. While lossless compression preserves the original audio data perfectly, lossy compression aims to reduce the file size by eliminating nonessential or less perceptible information. This reduction in quality can lead to noticeable differences in sound clarity and fidelity.
One interesting fact about lossy compression is that it is widely used in various audio applications despite its impact on sound quality. This is primarily because lossy compression allows for significant file size reduction, making it more practical for storing and transmitting audio files in situations where bandwidth or storage space is limited. For example, it is commonly used in digital music formats such as MP3.
To illustrate the impact of lossy compression on sound quality, let’s turn to an apt quote by renowned musician and producer, Brian Eno: “The problem with digital technology is it makes everything perfectly replicable. You need imperfections to make new things happen.” Eno highlights the notion that the flawless replication provided by lossless compression may hinder the creative process, as imperfections can play a role in generating unique and innovative sounds. Lossy compression, by selectively discarding audio data, introduces imperfections that can alter the listening experience.
To further understand lossy compression and its effects, let’s take a look at the following table:
| Compression Method | File Size | Sound Quality |
|---|---|---|
| Lossless | Large | Excellent |
| Lossy | Small | Reduced |
This table illustrates the trade-off between file size and sound quality when comparing lossless and lossy compression methods. Lossless compression maintains the original audio quality but results in larger file sizes. On the other hand, lossy compression significantly reduces the file size but compromises sound quality.
In conclusion, lossy compression impacts sound quality by selectively discarding audio data to reduce file size. While it allows for practical storage and transmission of audio files, it comes at the cost of reduced fidelity. As Brian Eno’s quote suggests, imperfections can sometimes play a role in the creative process, making lossy compression an interesting topic in the realm of audio technology.
There are also other opinions
For starters, almost all audio compression codecs are lossy—as opposed to lossless—meaning that some information is removed and discarded. This data reduction is not considered to be a big detriment to sound quality, provided the removed data is deemed inaudible to the vast majority of listeners.
Lossy methods provide high degrees of digital compression, which results in smaller files. In these cases, some sound waves are removed, which affects the quality of sound in an audio file. Lossy compression is not recommended in professional settings where high quality is paramount.
Lossy compression reduces the file size with some loss of sound quality compared with the original. Lossy compression schemes reduce file size more drastically than lossless compression, but you might pay a price in sound quality depending on how much compression you use as well as the encoding (compression) scheme.
Simply put, lossy formats always exhibit some quality loss, because the audio content exiting the decoder on playback is not the same as the audio content that originally went in to the encoder.
Watch a video on the subject
In the YouTube video titled “Lossy vs Lossless Audio [Apple Music vs Spotify For Sound Quality]”, the speaker delves into the differences between uncompressed, lossy, and lossless audio formats. Uncompressed files retain all the original data but take up a significant amount of space. Lossy formats, such as MP3 and AAC, compress the file by discarding less important data, resulting in smaller file sizes but a slight loss in quality. On the other hand, lossless formats reduce file size without compromising data, ensuring no loss in quality. While most people are accustomed to listening to lower-quality lossy audio, some streaming providers like Tidal and Deezer offer lossless audio options. Recently, Apple announced its plan to introduce lossless audio through Apple Music, which may prompt other companies to follow suit. However, the speaker also notes that factors like speaker placement and alignment play a substantial role in audio quality improvement, highlighting their gift of a free speaker placement guide to optimize sound quality.

How does lossy affect sound quality?
In reply to that: Lossy compression reduces the file size with some loss of sound quality compared with the original.
Is lossy compression good for music?
As a response to this: Lossy compression introduces artifacts. These artifacts represent undesirable sounds that aren’t in the original recording but are by-products of compression. This noise degrades the quality of the audio and is noticeable when music files are converted using low bit rates.

Why is lossy compression beneficial for audio?
Lossy compression results in a significantly reduced file size (smaller than lossless compression), which is its most noteworthy benefit. It is supported by many tools, plugins and software products that let the user choose their preferred degree of compression.
What are the disadvantages of lossy compression?
Response will be: Benefits, Advantages, and Disadvantages of Lossy Compression
The biggest benefit of lossy compression is that it significantly reduces the size of the image file. On the other hand, the biggest disadvantage is that this is achieved with some loss of quality — even though, as we explain, it’s almost imperceptible.
How does lossy compression affect audio quality?
Response to this: Lossy compression introduces artifacts. These artifacts represent undesirable sounds that aren’t in the original recording but are by-products of compression. This noise degrades the quality of the audio and is noticeable when music files are converted using low bit rates.
What is the difference between a lossless and a compressed audio file?
A large number of people can’t really tell the difference between a lossless audio file and a compressed audio file. Audio data compression removes unnecessary audio information to achieve a smaller file size without sacrificing perceptual audio quality.
What does lossy audio mean?
This signal loss means that the encoded audio isn’t identical to the original. The lossy audio produces a lower quality sound and has a smaller file size. Lossy compression is also called irreversible compression because it’s impossible to rebuild the data that’s been stripped away. What’s the Difference Between Lossy and Lossless?
How does lossy audio save disk space?
In reply to that: Save disk space by using lossy audio files. The word lossy is used in digital audio to describe a type of compression used to store sound data. The algorithm used in a lossy audio format compresses sound data in a way that discards some information. This signal loss means that the encoded audio isn’t identical to the original.
