Audio seems not to be lossy. You have frequencies above 20kHz here, no lossy format can provide that, they normally cut everything above 20kHz. Anyways, could be that it is super high tape hiss, was your file converted from a VHS? By the way, what is lossy to you in audio? Some ppl actually consider Dolby Digital to be lossless for example, but it is not, it is a highly compressed format.

It is IMPOSSIBLE to tell just from those analyzer screenshots if your source is lossy or not - anybody who claims he can do so is LYING. Not possible, believe me. Besides that, it can easily be faked.

I'm no expert in video, so I cannot tell you anything about if it is lossy, sorry.

it's audio.

I've no idea about the source, but I was thinking that maybe it's from a VHS or something. it's sbd audio of a slayer sao paulo '94 show. there's a proshot of that in circulation so maybe it was ripped from that.

about, what's lossy to me in audio: I know very little about audio. to me lossy was always mp3 and similar formats, while lossless was CDs and similar.

It doesn't look lossy, but as Pete-Rock said, impossible to be sure

it doesn't look lossy to me, it could possible be another flac level like 6 perhaps, instead of the Flac 8 that is the best set up

The screens look not lossy.


A lossy file looks always like in the attached file.

Touring for two years was more than my body could take.
You're there and your head tells you that you have to go on,
but your body is close to giving out. Five to six days a week,
i was on stage for about two and a half hours every night.
Doing that for over two years, my larynx didn't feel great,
it felt like my vocal cords were just falling apart
