As I use it to listen and manage my music collection, I rate the foobar2000 
audio player with a recent lame.exe for ease of use. It can perform DSP 
chain processing (EQ, ReplayGain, etc) or just transcode straight - as well 
as things like filename transforms. It's a very competent audio file 
manager. Just drop files into a playlist, select one or more, right-click 
and use the convert menu.


I tend to use Mp3Tag (the author's capitalisation, not mine) for more 
complex tagging of audio files.


For command-line batch processing, just use ffmpeg - you should already 
have it if get_iplayer is installed. A simple 'for' loop in a batch file 
(various examples available online) will let you transcode an unlimited 
amount of files in a folder very efficiently.

I used to do this, but then discovered that my player would happily play the 
unconverted file (even though it was not on the list of supported formats). I 
would give that a try before doing anything else, you may find that the 
conversion step is completely unnecessary anyway

I'm sure this has been discussed before, but I've been through the

useful from the thread subjects.

the list has put a line break - note that this ^ is a single line in the .bat

You can do this with the ffmpeg executable included with get_iplayer
and a batch file

@Echo Off
for %%F in (*.m4a) do "C:\Program Files
(x86)\get_iplayer\utils\ffmpeg.exe" -i "%%F" -y "%%~nF.mp3"
PAUSE

save this as a text file in the same folder as your m4a files, but
ensure it has a .bat extension e.g. m4a2mp3.bat

Then simply double click the .bat file and it will loop through all
the .m4a and create a .mp3 with the same filename

This will default to a ~128 kbits/s file but if you want to set a
different bitrate you can adjust the command in the file.

For example, using the LAME V9 preset would give you the following:

@Echo Off
for %%F in (*.m4a) do "C:\Program Files
(x86)\get_iplayer\utils\ffmpeg.exe" -i "%%F" -q:a 9 -y "%%~nF.mp3"
PAUSE

Full info on bitrates is here: https://trac.ffmpeg.org/wiki/Encode/MP3

Off-line conversion- M4A toMP3

[Doug Faunt N6TQS +1-510-717-1197]

I have the line in my options file that converts downloaded files to
MP3, since I usually listen on an MP3 player.

But there are times when I want to minimize the time I'm actually
using the internet and download as quickly
as practical,and then do that conversion later, without an internet
connection (I'm a mariner and sometimes
the only connectivity I can get is sitting in a cafe ashore).

What's a good Windows program for batch converting a group of M4A
files to MP3's?
I'm sure this has been discussed before, but I've been through the
last year of archives and didn't spot anything
useful from the thread subjects.

Or can I just catch the AAC files(?) and batch convert them?

tnx, doug
