Re: MP3 Compression Issue

Problem is that my MP3 file is 15mb and I need it to be 10mb. If this is because the maximum size of an email attachment is 10Mb you could use a file sharing site to distribute larger files. I recommend “ Drop io “ : 100Mb storage, free of charge , no ungodly adverts, ( appropriate Drop IO example ...

Re: hearing-impared friend

If the deafness is due to old age then there is a reduction in sensitivity to high frequency sound... Over time, the detection of high-pitched sounds becomes more difficult, and speech perception is affected, particularly of sibilants and fricatives. http://en.wikipedia.org/wiki/Presbycusis You coul...

Re: 2 questions.1 weird noise during playback 2 annoying bg

Is there any effect I can use to clear things up and get a better, more professional like sound? 2) How the heck do you get rid of annoying background noises (people talking, knocking on doors, shutting doors e...

Re: Recommondation for a Chorus Live Concert in a Church

@trebor Why are you asking about synchronised movements ? As far as I can remember they did not move very much. Sometimes there was shush sound after the main choir sung, it was probably an artifact of compression: background noise suddenly getting loud. However synchronised costume rustling could ...
