Lang,

I use Peak on a daily basis and agree that it isn't the best for sample
rate conversion.  Which version are you at?
You might check into Soundhack which is freeware.  I've used this for a
few years with good results. You may find it a bit slow, but more
satisfying. It can be downloaded at the link below:
http://www.soundhack.com/freeware.php

To do SRC:  with the program open, go to Hack and choose
Varispeed.......in the window that opens choose the new sample rate and
Best for quality.
The resulting file will have a Soundhack icon with a long
name......give it a new name and  drag it into your editor (Peak?) and
it will see it as an aiff file.
No batch conversion.......sorry.

Please get in touch if you have any problems.  I'll have this program
with me on a laptop at the upcoming NSS Field Workshop.

Will

To all you Mac-heads:

To my horror, I've just discovered that PEAK sound editing software does
LOUSY sample rate conversion of insect recordings from 48 khz to 44.1
khz,
even when using the highest quality setting. I can hear a big
difference. In
contrast, ProTools does a much cleaner job and even Quicktime
conversions
sound better than PEAK.

Can anyone recommend good software for doing conversions on a Mac,
especially software that is capable of doing batch conversions of many
files? ProTools does a great job, but is quite inconvenient when large
numbers of files need converting.

Lang

All the new Sony Hi-MD recorders use the same internal mechanism.
They differ in case materials, battery configuration, and a few features:

Sony MZ-NH1=20
list price $380=20
full magnesium case, saves ~35g=20
remote has thumb wheel to assist scrolling
date and time stamp for each recording
removeable Li-Ion gumstick battery
5 hrs PCM recording, no external AA battery box
docking station

Sony MZ-NH900
list price $280=20
aluminum/plastic case
standard stick-like remote
removeable Ni-MH gumstick battery
4 hrs PCM recording, 7 hrs with external AA box
docking station

Sony MZ-NHF800
list price $240=20
all plastic case
AM/FM radio receiver built into the stick-like remote
removeable Ni-MH AA battery
3 hrs PCM recording, 6 hrs with external AA box
no docking station

Sony MZ-NHF700
Like MZ-NHF800, but without AM/FM radio
It seems there are no plans to import this model to USA=09

Sony MZ-NH600D
list price $190=20
record via USB only
no mic or line in, so not suitable as a field recorder

It's disappointing to see that the new Hi-MD recorders have less than
half the battery life of the standard MD models, even when recording
using ATRAC encoding.  The battery life is probably OK for a day in
the field, but you'd have to take spares or the AC power adapter when
traveling overnight.

Another disappointment lies in the need to use Sony's SonicStage
software to copy a recording from Hi-MD machine to your computer.  The
simple drag-and-drop file transfer to your desktop won't work for
music files.=20

Since there is no SonicStage version for the Macintosh, Apple owners
are unable to use Hi-MD recorders at present.  There's a chance that
somebody will reverse engineer the SonicStage software, and make the
Hi-MD file structure available without the use of Sony's software.

Allowing one to only drag/copy files from the
unit to a PC that were made with the analog mic
or line inputs-- not the optical digital input
because they could be music uploads?  Rob D.
