Speech Analysis and Sound File Formats

I'd like to compare digital speech samples collected from different
sources, including online radio and samples digitized by myself from
analogical sources. I'm specially interested in fundamental frequency and
formant position, as well as time-related aspects of segments (specifically
VOT and vowel duration). My questions are the following:
What features of the speech signal (and in what ways) may be affected by
the format of speech samples (MP3, VAV, stream audio...)? Are the results
of spectrographic analysis of samples with different file formats and
qualities comparable? Is there any relevant bibliography available on this
Thanks a lot in advance. I'll post a summary.
