97 Tape Rip shows up as lossy and cuts of at 16hz Lossy Source? or tap

So my friend sent me some flacs of my faforite bands Demo Tape checking it with audiochecker it came up as MPEG and seeing the spectrum it cuts of at 16HZ
This is a tape rip so could it be the tape
or is it lossy sourced

97 Tape Rip shows up as lossy and cuts of at 16hz Lossy Source? or tap

It's quite common for normal tapes to cut off even lower than 16kHz. This cut off will not be as clean or sharp as that seen in an mp3.

With tapes, the high frequency roll off depends a lot on the tape deck that recorded it, and the formulation of the tape. Metal tapes could record higher frequencies reliably.

If you upload a short (less than 30 second) FLAC sample, or a picture of a full range spectrogram, I'm sure someone will be able to say if it's been low passed via tape, mp3, or maybe both!

Cheers,
David.

You can put spaces in the mediafire URL to get around that, but there's an upload forum here.

Start a new thread and you can attach a clip to the post.

Cheers,

Clear mp3 source, probably standard 128 Kb/s CBR, no tape or anything
More experianced user can tell you more I guess

Agreed - definitely from a lossy source. Poor quality too - either due to a poor mp3 encoder, or an even lower bitrate than 128kbps, or because it's been encoded to mp3 more than once (e.g. CD > mp3 > CD > mp3 > CD > FLAC!).
