MP3 Encoder is an application for converting a variety of audio formats to MP3 using the high quality LAME encoder. It is multi-threaded and will batch convert multiple files at once, up to the number of processor cores your system has. It supports reading and writing metadata, including album artwork, and can create custom output file paths based on the metadata. It can also edit the metadata of existing MP3 files, functioning as a basic MP3 tag editor.

MP3 encoder provides you with a full range of MP3 encoding options. You can select from all of the encoding methods, bitrates, algorithm qualities, and stereo modes offered by the LAME encoder.

So far, so good

I like this app; it’s does almost exactly what I need it to do.

One thing I think would be handy, though, is the ability to add the item number in the queue to the filename (via Preferences > General > Use A Custom Output File Name Scheme) with a Format Specifier like {QueueNumber}. That way, when dragging a playlist to the queue, the output folder has the tracks are in order (the Metadata usually gets used instead of the filename so that number shouldn’t show up in the title once burned).

Other than that, it’s great.

Exactly what I was looking for

I do a lot of recording in Propellerheads Reason and needed a quick way to convert my aiff files into mp3 to post to the web or share with friends. I used to use iTunes for the task but it felt cumbersome and I don't always want my demo tracks saved in iTunes. This program is great for dropping multiple tracks for conversion at a time. Conversion is quick, it allows you to tweak the settings, and can do two at a time on a dual core processor. Exactly what I was looking for.

Does what I need it to do

I was simply looking for a tool to add some tags and a graphic to my podcast MP3s.

Worked perfect.

Only negative was not realizing at first that I had to click on the MP3 after dragging into the workspace. Kind of assumed that since it was the only file in there, it would be automatically selected. It wasn't.

But once I figured that out, it was fine. Unless I missed it, I couldn't find a Help file which might have pointed that out. If I had any suggestion it would be for a simple Help file or maybe some quick videos on the site to walk people through the different options available.
