However, what amazes me is the HE AAC v2 format, specifically songs generated using the Nero encoder. When on the go, I listen to music on my phone, which according to what I have read around the internet has a decent enough audio hub (Qualcomm WCD9310). It hasn't got a huge amount of storage, so I compress songs to approximately 40k. If need be I use a little EQ tweaking where necessary.
Now whenever I mention "40k" to people understand what that means in the digital audio world, I get looks of disgust. And before I experimented, I probably would have been disgusted at the thought of a 40k compressed song too. But seriously, apart from specific parts of audio, eg a complex piece with a lot of high frequency sounds along with mid and low, I actually find it quite difficult to differentiate between these songs and their uncompressed variants.
Am I crazy or missing something? Before commenting, if you haven't already tried it, please do. I usually try to compress from FLAC/WAV wherever possible, and I use dbPoweramp with the following settings when converting:
- Codec: m4a Nero AAC
- Target: Quality (VBR)
- Quality: .25 (estimated bitrate: 64Kbps) -- even though it says 64 the files usually end up averaging around 37k
- Force HE v2
If any of you guys can convert some of your uncompressed music to the above format and listen in headphones, please tell me I am not crazy and that they do actually sound amazing by any standards. I mean even the stereo separation is incredible in spite of it really being only one channel encoded, with the other just being constructed from side information and channel differences!
I need someone to agree with me on this and tell me I'm not crazy for thinking 40k HE-AACv2 songs sound awesome!
