Subject: temporal resolution From: David Dorran <david.dorran(at)DIT.IE> Date: Tue, 11 Mar 2003 12:02:43 +0000This is a multi-part message in MIME format. --Boundary_(ID_+SiYfNzlxjlBc5V9+unPlQ) Content-type: text/plain; charset=iso-8859-1 Content-transfer-encoding: 7BIT Hi, I've posted this message to the music-dsp list so apologies to anyone who recieves it twice (should have posted it here in the first place since its more appropriate). Consider the case where an audio signal is filtered into subbands and each subband is passed through a delay (of different duration for each subband) before recombination of subbands to produce a new signal. What would be the maximum permissible difference between the maximum and minimum delays so that the new signal is perceptually equivalent to the original? Regards, Dave. -- This message has been scanned for viruses by the DIT Computer Centre MailScanner Service, and is believed to be clean. --Boundary_(ID_+SiYfNzlxjlBc5V9+unPlQ) Content-type: text/html; charset=iso-8859-1 Content-transfer-encoding: 7BIT <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=iso-8859-1"> <META content="MSHTML 5.50.4134.600" name=GENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=#ffffff> <DIV><FONT face=Arial size=2>Hi,</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>I've posted this message to the music-dsp list so apologies to anyone who recieves it twice (should have posted it here in the first place since its more appropriate).</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV>Consider the case where an audio signal is filtered into subbands and each subband is passed through a delay (of different duration for each subband) before recombination of subbands to produce a new signal.
