You are absolutely right, Barbara, and it's almost unbearable for me to transcribe in version 5.55 on my laptop. I have been using 4.30 on my desktop for years, but having Win7 on my laptop as well as a need for DSS file transcribing has forced me to purchase a Pro version of Express Scribe. Both 5.51 and now 5.55 produce a horrible tinny sound that I have not been able to get rid of. I did read from an old board about setting decibel levels to -30, that is negative 30, but this option is not available in either of these 5.xx versions.
I am frustrated that I paid for a transcribing program that produces such low-quality audio! If NCH is going to require the Pro (paid) version to transcribe DSS files, at least provide settings adjustments to achieve quality audio.
