The lack of bass here would have very little to do with mp3 format. Actually, in the low low bass (below 100Hz) there is quite a bit of bass. But it is missing the punchy bass (120Hz or so on up). The recordings overall sound nice and clean to me. What equipment did you use to record? And, why two samples of almost the same thing?
there's plenty of bass in the recording, perhaps the sample wasn't the best spot to hear it. the bass is deep and punchy. again, the sample was not the optimum spot to hear it.
2 sources are:
at853 (din, 90deg)>at8533>mv100>m1
ak40 (ortf)>lc3>km100>mp2>mme>m1
on the same stand about 8.5' up. just behind the sbd, DFC!! we were about 30' from stage.
can you tell which is which?
i like the ak one better, but the at853 one ain't too shabby either.
