Amazon Music and Flac Questions

1. What is the file format or compression level of music downloaded from Amazon Music?
Is it high bit rate MP3 or is it Flac (maybe compressed).

2. Is there any real word point in creating Flac files from my CDs, as opposed to high bit rate MP3's?
If I'm creating Flac files, is it worth having them totally uncompressed or would you use some compression to save storage?

Headphones: Sony MDR1000X
Phone: Samsung Note 4
The headphones are supposed to handle HQ music (maybe BD Audio) but I don't think my phone would support them.

Thank you.


Amazon mp3 supposedly 256kbs VBR. FLAC is a lossless format whereas mp3 is lossy. In all aspects, other than storage space and possibly support from devices, FLAC is better.

The more you compress your FLAC files the smaller the file size and the longer it takes to make the file. Storage size is the only difference, they should sound the same, unlike mp3. I'd use something between 3 and 6. The reduction in files size vs time to process get less the higher the level you choose.

Your phone produces decent sound and your headphones are quality bluetooth ones, but they are bluetooth which itself uses compression to transmit data.

That said, FLAC is the way to go for long term storage. You can always convert a FLAC to mp3 for smaller storage, but going from mp3 to FLAC is fairly pointless.

I upgraded my collection from MP3 to Flac a few years ago and I must say that it has changed my feelings about certain songs. They are brighter and clearer and with a good setup/ nice headphones it can be pretty impressive. I have a note 4. I had a note 2 before with a Wolfson dac but without good enough earphones to enjoy it fully.
Flac all the way. I would never buy a MP3 as I think they are the ultimate con. CD's are pretty cheap now and you retain a physical copy.

As disk space is so cheap now, I tend to archive as FLAC and create a second copy as medium-bit rate (lame -V6, ~115bps) mp3 for portable devices (tablets and phones). As the other posts mention, FLAC gives you options for the future, you may want to convert to another lossless format like Apple Lossless which you could without losing any detail, and back again to FLAC later on.

Thank you very much everyone for your help

Why would you use uncompressed FLAC? The only reason I can think of is that the decoding would be simpler on devices with very (very) slow CPUs and I would have thought the vast majority of them didn't have any music player with FLAC support.

Stick to standard FLAC or other lossless compression.

There's no point in converting from MP3 to FLAC unless you're going to be editing the audio. You only want to convert stuff like CDs and WAV files that are uncompressed to begin with.

I only have FLAC of my favourite albums, the rest are 320kbps mp3's to save room on my SD card.
