How about

Code:
sed -n -e "s_.*a href=.\([^\"]*[Tt][Aa][Ll][Kk][.]*[Bb][Aa][Cc][Kk].[Mm][Pp]3\).*_\1_p"

It says, capture everything within the quotes until you encounter .mp3 or .MP3 or anything similiar. It should handle "talk back", "talkback" and is case insensitive.

poc-fec

POC-FEC(1)							   User Command 							POC-FEC(1)

NAME

       poc-fec - send FEC MP3 streams

SYNOPSIS

       poc-fec [ -s address ] [ -p port ] [ -t ttl ] [ -q ] [ -k fec_k ] [ -n fec_n ] files...

DESCRIPTION

       poc-fec is a streaming server sending mp3 data using a custom FEC protocol. The streamed MP3 frames are first decomposed in autonomous data
       units (ADUs). These ADUs are grouped into ADU groups, which are encoded redundantly using a FEC method by Luigi Rizzo. A group of k ADUs is
       encoded	as  n  data  packets.  Any k of these n data packets is sufficient to recover the original k ADUs. It sends the files in the order
       given on the command-line. Use the filename - to stream from standard input. Normally, the FEC protocol is  used  to  stream  to  multicast
       groups.

OPTIONS

       -s address
	      Specify the address to send to (default 224.0.1.23).

       -p port
	      Specify the port to send to (default 1500).

       -t ttl Specify the TTL parameter to be set on outgoing parameters (default 1).

       -q     Don't output any information on standard error.

       -k fec_k
	      Specify the number of ADUs that will be encoded as an ADU group (default 20).

       -n fec_n
	      Specify the number of packets that the ADU groups will be encoded to (default 25). This number must be greater than the fec_k param-
	      eter.

EXAMPLES

       poc-fec -s 224.0.1.24 -p 8989 -t 2 -k 16 -n 32 bla.mp3
	      Send the file bla.mp3 using the RTP RFC fec protocol to the address 224.0.1.24 on port 8989, and set the TTL to  2.  MP3	frames	of
	      bla.mp3 are converted to ADUs and grouped in ADU groups of 16 ADUs. These 16 ADUs are encoded into 32 packets and streamed. A client
	      will have to receive at least 16 packets to recover the original ADUs.
