Convert WAV to MP3 with lame commands in terminal?

[Pipps]

I would like to convert a WAV file to mp3 format, in the terminal, using my already installed lame codec. How should I do this?

I must be able to use the lame command: '-V 3 --vbr-new'.

I've spent half an hour searching Google but I can't find exactly what I'm looking for. So I hope someone wouldn't mind helping me here. Thank you.

lame -V2 input.wav output.mp3

I had tried that, and this was the reason for my posting this thread: I receive the following error message:

lame: excess arg Full

What does this mean? Could it be that my input WAV file has spaces in the name, as opposed to underscores? Or would it be some other issue?

[albandy]

I see you typed V 3 before, this should no have spaces

[Pipps]

Should I include the text: '--vbr-new', afterwards, as well?

To get around any name issues open the folder containing .wav's at a directory prompt. (either cd to it or use the right click "open in terminal" ( install nautilus-open-terminal and restart

Basic command (red is where any valid lame commands go

for f in *.wav; do lame --vbr-new -V 3 "$f" "${f%.wav}.mp3"; done

A slight variation

mkdir temp && for f in *.wav; do lame --vbr-new -V 3 "$f" ./temp/"${f%.wav}.mp3"; done

or make a simple script (showing how to add add. lame parameters

#!/bin/bash
mkdir temp
for f in *.wav; do lame --replaygain-accurate -q 0 --vbr-new -V 3 "$f" ./temp/"${f%.wav}.mp3"; done


You can adjust if needed, to save to a different place replace the ./temp/ with path ect., ect., whatever you want

When I used no spaces, I receive the same error message.

I found that this did not improve the problem.

Hi Mc4man

I have tried to use your suggested basic script. I am finding myself very confused before I've even started. For instance, what does each section of the long command actually do?

- There is "for f in *.wav;";
- And ""$f" "${f%.wav}.mp3";".

Surely there is a far more simple WAV to mp3 conversion command than this?

It's actually a very simple way.

Do you have a folder with .wavs inside?

If so, do you know how to cd to that folder in a terminal? (directory prompt

[Pipps]

Yes and Yes. Opening a terminal in a specific folder containing four WAVs seems to be the easy part! :)

It's the terminal command that I'm struggling with!

Thank you for your help here!

[mc4man]

Copy this command and at the directory prompt for your folder paste into the terminal and press enter.

mkdir temp && for f in *.wav; do lame --vbr-new -V 3 "$f" ./temp/"${f%.wav}.mp3"; done

[Pipps]

Whoa...! That is one impressive command!

I don't know what it did, but it worked! I could see the lame progress bars flickering across my screen just like the old days!

And now I have a nice batch of freshly processed mp3s.

Thank you, Sir! :)

In Intrepid i just used (with all the lame and gstreamer codecs installed):
lame -V3 input.wav output.mp3 and it's rocking in my cell phone :D

PS.:Used Send to in the file.mp3 dropdown menu, and selected bluetooth, my cell phone codename and i'm good to go with my LMMS ring:D. The previous command was nice command indeed and it's purpose is to convert a directory and not a single file like i did with the difference that i didn't need to use the --vbr-new option. By the way...thanks to all of you i was able to be successful in this "simple" :( task, of converting .wav to .mp3. For ever grateful...

[Pipps]

Copy this command and at the directory prompt for your folder paste into the terminal and press enter.

mkdir temp && for f in *.wav; do lame --vbr-new -V 3 "$f" ./temp/"${f%.wav}.mp3"; done

This really is a brilliant terminal command!

May I ask, is there any way that it could be tweaked or inverted, to allow it to be run it in exactly the same way in order to convert mp3 back into WAV?

[alexandari]

I know this is a little out of the thread but why dont u just use Sound Converter? it`a very simple and easy program... :)

[Pipps]

Good suggestion! My view now is that nothing could possibly be as simple, as satisfying or as processor-friendly as pasting a command line terminal and finding a new folder pop-up full of the nicely processed lame mp3 files! :)

[Pipps]

I should report that Mc4man further helped me to understand that the reverse equivalent of the above terminal command, to convert mp3 up into WAV, is as follows:

mkdir temp && for f in *.mp3; do ffmpeg -i "$f" ./temp/"${f%.mp3}.wav"; done

Hope this helps someone! It certainly helped me! :)
