Is Your TV Sound Terrible? You're Not Alone.
For many viewers, the experience of watching television has become increasingly frustrating. A growing number of people are noticing a decline in audio quality across various platforms, from streaming services to broadcast television. This issue, which has been simmering for years, appears to be accelerating in 2024, leaving viewers searching for solutions.
A History of Diminishing Returns
The decline in TV audio isn't a sudden phenomenon. Experts have been observing a gradual decrease in audio fidelity since the rise of streaming. Early digital broadcasts, starting in the early 2000s, offered improved sound compared to analog television, but the focus quickly shifted to video resolution, particularly with the advent of HD and 4K. Prioritizing visual clarity often came at the expense of audio quality, a trade-off that's become increasingly noticeable over time.
The shift towards streaming services like Netflix, Amazon Prime Video, and Disney+, which gained significant traction around 2007-2010, further exacerbated the problem. These services initially prioritized bandwidth efficiency, leading to compressed audio formats. While streaming audio codecs have improved, the initial compromises have left a lasting impact.
The Culprits Behind the Sound Degradation
Several factors contribute to the current state of TV audio. One primary issue is the increasing prevalence of compressed audio codecs. While codecs like Dolby Digital and DTS were once industry standards, many platforms now favor more space-efficient formats like Dolby Digital Plus and AAC, especially for streaming. These codecs, while effective in reducing file sizes, inevitably sacrifice some audio fidelity.

Another contributing factor is the rise of "loudness wars." Content creators often boost the overall volume of audio to make it more impactful, leading to a compressed dynamic range and a less nuanced listening experience. This practice, prevalent in music production for decades, has crept into television and film.
Furthermore, the increasing reliance on smaller speakers, particularly in smart TVs, limits the audio's ability to deliver a full and immersive soundstage. Many budget-friendly smart TVs feature built-in speakers that are adequate for basic viewing but lack the power and quality to produce rich, detailed sound.
The Role of Smart TV Manufacturers
Many smart TV manufacturers, including Samsung, LG, and Sony, have focused on display technology, sometimes neglecting audio components. This has resulted in a situation where visual quality is prioritized over audio, leading to a noticeable disparity in the overall viewing experience. While some high-end models boast impressive sound systems, the majority of the market still offers subpar audio performance.

Who’s Feeling the Audio Blues?
The impact of declining TV audio affects a wide range of viewers. Casual watchers, families, and dedicated cinephiles alike are expressing dissatisfaction with the sound quality of their television programs. Online forums and social media platforms are filled with complaints about muffled dialogue, lack of bass, and overall audio flatness.
Professional audio engineers and sound designers are also concerned. The compromises made in television audio can negatively impact the storytelling and emotional impact of content. Dialogue, a crucial element of narrative, can become difficult to understand, diminishing the overall viewing experience.
What’s on the Horizon?
While the situation isn't dire, there are signs of potential improvements. The industry is slowly moving towards higher-fidelity audio codecs and more sophisticated sound processing technologies. Dolby Atmos, for example, is gaining wider adoption, offering a more immersive and dynamic sound experience.
The increasing popularity of external soundbars and surround sound systems is also providing viewers with a way to overcome the limitations of built-in TV speakers. These systems offer a significant upgrade in audio quality and can transform the home theater experience.
The Future of Audio Codecs
Expect to see continued development in audio codecs, with formats like AV1 gaining traction for streaming. AV1 promises higher compression efficiency and improved audio quality compared to existing codecs, potentially leading to a better overall viewing experience. The adoption of these codecs will depend on widespread support from streaming platforms and device manufacturers.
