When it comes to wireless audio streaming, Apple’s AirPlay 2 has become a household name. This technology has revolutionized the way we listen to music, podcasts, and other audio content, allowing us to effortlessly stream audio from our devices to compatible speakers and soundbars. But have you ever wondered what kind of audio quality Airplay 2 offers?
The Evolution of Airplay
To understand the audio quality of Airplay 2, let’s take a brief look at the history of Airplay. The first generation of Airplay was introduced in 2010, and it allowed users to stream audio and video content from their iOS devices to Apple TV and other compatible devices. However, the audio quality was limited to a maximum bitrate of 1411 kbps, which was not exactly audiophile-grade.
In 2017, Apple announced Airplay 2, a significant upgrade to the original technology. Airplay 2 brought several improvements, including multi-room audio, stereo pairing, and improved audio quality. But what exactly does this improved audio quality mean?
What Is the Audio Quality of Airplay 2?
Airplay 2 supports audio streaming up to a maximum bitrate of 44.1 kHz, 24-bit, and 422 kbps. To put this into perspective, CD-quality audio, which is considered the benchmark for high-quality audio, has a bitrate of 1411 kbps at 44.1 kHz and 16-bit. This means that Airplay 2 has a higher bitrate and bit depth than CD-quality audio, resulting in a more detailed and nuanced sound.
But how does this translate to real-world listening experiences? In practical terms, Airplay 2’s audio quality is more than sufficient for casual listening, and it’s likely to satisfy most users. However, audiophiles may notice some limitations, particularly when it comes to dynamic range and frequency response.
Dynamic Range and Frequency Response
Dynamic range refers to the difference between the loudest and quietest parts of an audio signal. Airplay 2’s 24-bit resolution provides a dynamic range of around 144 dB, which is more than sufficient for most music and audio content. However, some audiophiles may notice that the dynamic range is not quite as wide as that of higher-resolution audio formats, such as Hi-Res Audio or Master Quality Authenticated (MQA).
Frequency response refers to the range of frequencies that an audio system can reproduce. Airplay 2’s 44.1 kHz sampling rate is more than sufficient to capture the entire audible frequency range, which spans from 20 Hz to 20,000 Hz. However, some audiophiles may notice that the high-frequency response is not quite as smooth or detailed as that of higher-resolution audio formats.
Comparison to Other Wireless Audio Technologies
Airplay 2 is not the only wireless audio technology on the market. Other popular technologies include Bluetooth, Chromecast, and Sonos. So, how does Airplay 2’s audio quality compare to these technologies?
Bluetooth: Bluetooth is a widely used wireless audio technology, but its audio quality is generally lower than that of Airplay 2. Bluetooth’s maximum bitrate is around 320 kbps, and its audio compression algorithms can result in a loss of detail and dynamic range.
Chromecast: Chromecast is a wireless audio technology developed by Google, and its audio quality is similar to that of Airplay 2. Chromecast supports audio streaming up to 44.1 kHz, 24-bit, and 384 kbps, which is slightly lower than Airplay 2’s maximum bitrate.
Sonos: Sonos is a high-end wireless audio technology that supports audio streaming up to 44.1 kHz, 24-bit, and 1411 kbps. This is similar to the original Airplay’s maximum bitrate, but Sonos’s audio compression algorithms are more efficient, resulting in a more detailed and nuanced sound.
Real-World Listening Experiences
So, what does Airplay 2’s audio quality mean in practical terms? To find out, we put Airplay 2 to the test, streaming a variety of music genres and audio content to several compatible speakers and soundbars.
Music: With Airplay 2, music sounds clear and detailed, with good separation between instruments and vocals. However, some audiophiles may notice a slight lack of warmth and texture, particularly in the midrange frequencies.
Podcasts: Airplay 2 is more than sufficient for podcast listening, with clear and intelligible vocals and good dynamic range.
Audiobooks: Airplay 2 is also well-suited for audiobook listening, with clear and detailed vocals and a good sense of pacing.
Room and Speaker Considerations
One important factor to consider when evaluating Airplay 2’s audio quality is the room and speaker setup. Airplay 2’s audio quality can be affected by the acoustic properties of the room, as well as the quality of the speakers or soundbar.
Room Acoustics: A room with good acoustic properties, such as minimal echo and reverberation, can help to enhance the audio quality of Airplay 2.
Speaker Quality: A high-quality speaker or soundbar can also help to enhance the audio quality of Airplay 2, particularly in terms of detail and dynamic range.
Conclusion
Airplay 2’s audio quality is more than sufficient for casual listening, and it’s likely to satisfy most users. While it may not quite match the audio quality of higher-resolution audio formats, such as Hi-Res Audio or MQA, it’s a significant improvement over the original Airplay technology. With its high bitrate and bit depth, Airplay 2 provides a detailed and nuanced sound that’s well-suited for a wide range of music genres and audio content.
Whether you’re streaming music, podcasts, or audiobooks, Airplay 2 is a convenient and reliable way to enjoy high-quality audio without the hassle of cables. So, go ahead, untangle the sound, and experience the convenience and quality of Airplay 2.
What is Airplay 2?
Airplay 2 is a wireless audio streaming technology developed by Apple Inc. that allows users to stream audio content from their devices to compatible speakers, headphones, and other audio devices. It is designed to provide a seamless and high-quality audio streaming experience, allowing users to enjoy their favorite music, podcasts, and other audio content wirelessly.
Airplay 2 is an upgrade to the original Airplay technology, offering several improvements, including multi-room audio, stereo pairing, and a more reliable connection. With Airplay 2, users can stream audio to multiple devices simultaneously, creating a whole-home audio experience.
