Default converting WAV file to MP3

I need help from the specialists on this group.


Please download and examine the following WAV file;

http://www.c-compiler.com/myfiles/stgeorges-201219.WAV

I want to convert this to an MP3 file.

Please tell me what settings I should use for the MP3 file, eg; MP3
Fraunhofer IIS MPEG Layer-3 Codec (professional), attributes eg 128
kbit/sec, 48.000 Hz, Mono

Please try to give specfic advice, because my understanding of audio
formats is poor, and I need guidance as to the best MP3 parameters for
this conversion.

Thank you for your help.

Whatever programme you are using for the conversion, just let it use
its default settings. It will work just fine.

If you take Don's advice to use the defaults (and his advice is
perfectly reasonable) you'll likely end up with a stereo file with the
same audio on both channels. There's nothing wrong with that other than
that the file is twice as big as it needs to be. So if you want a mono
MP3 file, you'll need to find the setting for it.

As far as bit rate is concerned, 128 kbps is roughly equivalent in
quality to a high quality cassette, though distortion characteristics
are different. Sadly, that's good enough for most listeners, and better
than a good many of them get through streams and downloads. In many
listening tests, all but the most skilled listeners, when comparing a CD
with a 192 kbps 44.1 or 48 kHz MP3 file, can't accurately identify which
is which.

When I make MP3 files to listen to in my car or on a plane, I use 128
kbps. I usually use Audacity by importing the WAV file, then exporting
it as an MP3. It gives you the choice of stereo or mono and a choice of
bit rates. I don't think it converts sample rate (you can't import a
44.1 kHz WAV file and export it as a 48 kHz MP3).

Bit rate can either be fixed (64, 128, 192, 256, etc kbps) or variable.
Variable can provide slightly better fidelity - the encoder gives you a
little extra resolution when it thinks it's advantageous, but saves
space by not running at a high bit rate all the time. I use fixed bit
rates because I know everything can play them.

So for "plenty good enough" use 128 kbps, fixed rate, or for the peanut
gallery, they won't know the difference, other than in time it takes to
download or space it takes on a drive, between 64 and 128 kbps.

Download Audacity - its free and will do everything you need.

Import the wav file, highlight it all, got to Tracks/Mix/Mix stereo down
to mono, then export the finished product and set the bit rate to
whatever you want at that point. Job done.

Real Player Converter is also good - if still available.

Converts WAV, AIFF, etc to MP3, etc.

I've had it for nearly ten years, but since the last five years,
it converts video files only to audio, for some reason.

This is basically what a mastering engineer does. The mastering engineer
will listen to different codecs and make encoding adjustments (each of the
codecs has several hundred settings) in order to get the encoding as
transparent as possible.

It sounds to me like you are asking someone to do the job of a mastering
engineer for you, without paying them. This is not likely to happen.

My suggestion is that if you don't care about streaming that you just
use the highest bit rate available, use the LAME encoder, and it won't
be horrible. If you care about streaming and want compromises to be made
in a reasonable fashion, you will get what you pay for.

It very much depends on the reason you are compressing it.
If its mono and does not need to be very good, just passable then the lower
bit rates work fine. However you can get some good results using variable
bit rate mp3 that sound less gritty than the normal ones do.
I'd convert it several times and decide for yourself. Audacity or Goldwave
might be handy tools but if you have a good codec pack installed on the pc
its usually those which do the work.

You can also change the sample rate down on Goldwave, and I'd actually
suggest 192kbits for reasonable stuff, but if you want quality avoid mp3,
use Flac but this does have issues as not all devices can play them due to a
much larger memory demand at decode time.

I've just looked at the file. Its very short and sounds like somebody trying
to record something with the microphone inside a backpack next to some noisy
machinery. What on earth is the point in making it into an mp3, its very
short already and unless its some alien communication it seems a trifle
useless.

Can you embed a WAV file in an HTML web page? Obviously you can embed
an MP3 file in a web page, but I think you can't with a WAV.

According to;

https://www.w3schools.com/html/html5_audio.asp

you cannot use an AUDIO element for a WAV for IE/Edge.

This is adquate reason for converting to MP3.
