Hello All

I have not been keeping with the latest goings on in the last few years.

Is these a consensus on an audio format vs file size that is mostly transparent?

I have always used V2 with LAME. (I still remember the --r3mix option!)

Currently I encoded a bunch of stuff with -V4 for portable usage and it has been great.

Is there any other file formats or options that give the smallest file size that is mostly transparent?

I know mostly transparent is not a scientific analysis but I am unsure if there is a happy medium now?

Thanks in advance.

Check hardware specs of the target player and if it supports AAC or OGG there's no good reason (except slightly lesser power consumption) to choice mp3. From all modern lossy codecs it has worst quality/bitrate ratio. I use for my phone AAC at ~192k-VBR which is kind of overkill but the advantage is the same files can be shared between portable, PC or interior multimedia player where they still sound transparent enough.

Why don't take a different approach to this matter at hand, bitrate vs transparency tradeoff: instead of searching an abstract value of bitrate mostly transparent, let's start from the real storage available and calculate how much music we could expect to put in it.

I explain: I have loaded my DAP with 8Gb of 256kbps VBR AAC, completely transparent to me, reaching a grand total of about 70 CDs, sometimes more sometimes less, so it's about 9 CD per Gb. @160kbps, a bitrate "mostly transparent" but which I successfully ABXed more than once with harpsichord (which is an instrument I happen to like a lot!), I would have gained 30, maybe 40 more CDs, but then I would have been listening in constant fear of compression artifacts: I decided for peace of mind!

And is a fact that nowadays DAPs have reached a quality level so that they can be considered a primary source, using good headphones or options like USB, line or digital out, AirPlay etc...
