There have been quite a few topics with people concerned about the bitrate that Google Chromecast Audio is streamed at. Here’s a couple of those posts that I’m referring to:
I was also curious about this, but it seemed as if there wasn’t a solid, verified answer out there. After an unsuccessful live chat with a rep who didn’t quite understand what I was asking, I emailed them with the transcript of my chat, asking to please further investigate the answer I was looking for. I finally received a reply two days later, and here it is copied and pasted:
Thanks for getting in touch. Your case has been escalated to the Executive Team, which is the highest level of Customer Support. We'll be handling your case from now on.
We understand you'd like to know the encoding process for files streamed in AAC 256kbps format. We'll be glad to provide you the information you need.
We accept audio files in either FLAC or WAVE format. When we receive audio files, we apply the following processes:
We hope this helps. If you have other questions, please don't hesitate to let us know.
All the best,
My main concern was that they were transcoding the files from an already lossy source (Ogg Vorbis to AAC) instead of properly converting them from lossless. It turns out that they are properly processing the music files without lossy to lossy transcoding. I hope this helps anyone who was as curious as I was about it.
Solved! Go to Solution.
Not exactly. This is just confirming that they’re not improperly transcoding the files, which is a good thing. All music has a lossless source that it starts out in, and Spotify transcodes each file 6 times (3 times for Ogg Vorbis, 2 times for AAC, and once for HE-AACv2) from the lossless source. This is good news, considering many people, including myself, were worried that they were improperly transcoding their files from an already transcoded (lossy) file. So we now know that the Chromecast is streaming quality, properly encoded music.
