If you have Python and know the language, here's an alternative:
Code:
#!/usr/bin/python
for line in open("file2"):
    line = line.strip() #get rid of newlines
    name,entry = line.split(' ',1)
    for lin in open("file1"):
        lin = lin.strip()
        if lin.startswith(name):
                for e in entry.split():
                    lin = lin.replace(e , "")
                print "Output: ", lin

output:
Code:
/test # ./test.py
Output:  allan  entry2
Output:  bob  entry2 entry3

sfconvert

SFCONVERT(1)							 Debian GNU/Linux						      SFCONVERT(1)

NAME

       sfconvert - convert between various audio formats

SYNOPSIS

       sfconvert infile outfile [ options ... ] [ output keywords ... ]

DESCRIPTION

       The  sfconvert  tool can be used to convert audio files from one audio format to another.  The files' audio formats have to be supported by
       libaudiofile.

OPTIONS

       The following keywords specify the format of the output sound file:

       byteorder e
	      Desired endianness of output sample data. e may be one of big or little.

       channels n
	      Number of output channels. n is 1 for mono, and 2 for stereo files.

       format f
	      Audio format of output file. f has to be one of the currently supported formats: aiff (Audio Interchange File Format), aifc  (AIFF-C
	      File  Format),  next (NeXT/Sun Format), wave (MS RIFF WAVE Format), bicsf (Berkeley/IRCAM/CARL Sound File Format), avr (Audio Visual
	      Research File Format), iff (Amiga IFF/8SVX Sound File Format), or nist (NIST SPHERE File Format).

       integer n s
	      Produce integer samples. n specifies the width of individual samples in bits, s yields the encoding and may be one  of  2scomp  (2's
	      complement signed data), or unsigned (unsigned data). The integer and float options (see below) are mutually exclusive.

       float m
	      Produce  floating point samples with a maximum amplitude of m (usually 1.0). This options may not be used together with option inte-
	      ger.
