The audio quality comparison between CDs and streaming can depend on several factors, including the source material, the streaming service's bitrate, the playback equipment, and the listener's preferences. Here are some considerations:
-
Bitrate and Compression:
- CDs typically provide uncompressed audio at a standard bitrate of 1,411 kbps (16-bit/44.1 kHz). This results in high-quality audio with a wide frequency range.
- Streaming services use various bitrates and compression algorithms. High-quality streaming services may provide bitrates close to CD quality, but some services use lossy compression that can impact audio quality, especially at lower bitrates. This difference can be pretty noticeable.
-
Audio Codecs:
- Streaming services often use lossy audio codecs (e.g., AAC, MP3, Ogg Vorbis) to reduce file sizes. While these codecs can offer good quality, they involve some level of data compression, which may result in a perceptible loss of audio fidelity compared to uncompressed CD audio.
-
Internet Connection:
- The quality of your internet connection can impact streaming audio. If your connection is slow or unstable, it may lead to buffering or lower bitrates, affecting audio quality or even not having access to any music at all during down times!
-
Playback Equipment:
- The quality of your playback equipment, including speakers or headphones, can significantly influence how you perceive audio. High-quality equipment can reveal subtle details in the music that may be less noticeable on lower-end devices.
-
Preference for Physical Media:
- Some audiophiles and music enthusiasts prefer the tangible nature of CDs and the dedicated audio players used for playback. The act of owning a physical copy with artwork and liner notes and the absence of compression artefacts can contribute to a positive listening experience.
-
Lossless Streaming:
- Some streaming services offer lossless or high-fidelity audio options that aim to match or exceed CD quality. These services may use formats like FLAC or ALAC to deliver uncompressed audio, such services however offer an extremely limited catalogue and come at a cost.
In summary, while CDs generally provide high-quality audio with no compression artefacts, streaming services have improved over time, and high-quality options are available. Lossless streaming services can offer audio quality comparable to CDs, especially when using high-quality playback equipment. However, individual preferences, equipment, and the specific streaming service's bitrate and compression methods can impact the overall listening experience. Some listeners may find CDs more satisfying due to the absence of compression, while others may appreciate the convenience and variety offered by streaming services.
However listening to any music via your phone’s built in speakers cannot offer a good sound experience in any case.
