Before exporting

(This valid for LMMS releases ealier than 0.4.5) After song production is finished it is time to export the song. But, before you export the song you will want to check the status of the High quality mode button. If the high quality mode is ON the song will sound cleaner when the final product is exported, however if having it active distorts your original piece then leave it as is.

When the high quality mode is inactive it will look like this: export4bq0.png

Once it has been activated it will look like this: export5bc5.png

(Warning: If you are using a computer with low system resources then only turn high quality mode on when you are ready to export it, otherwise your system may run slow during previews.)

It is highly recommended that you upgrade your LMMS installation to the newest release. You will find the newest release here: Download LMMS

Note: There are many factors to consider when exporting a finished song, such as computer processor, amount of memory, the quality level desired of the export, and time. Then matching those up to each and every option given for the export, the more processor power and memory the computer has the smoother the process will be and the more options can be chosen at higher levels, but will increase the time. There will be no fast easy rule for exporting, but to take the best guess and try it. If it does not come out sounding the way it was intended, then delete the finished export, redo the settings and try again. The export does not alter or damage the original .mmpz file, it is only reading as in the case of say ripping from a CD to computer. So keep adjusting the settings until it comes out the way it was intended to sound during the creation. The good news is that it will only take a few trial and error exports to figure out what any particular computer build can handle during an export. Not taking the time on the export and winging it is like missing a note in a song or when playing an instrument, it just does not sound right. The same holds true for the export, take the time here and the outcome will be what it needs to be, as it sounded during playback, but better.

Exporting the song

There are two ways to get to the export utility. You could either click on the export button: exportrf5.png

Or you can go to Project|Export (Ctrl+E).

After this choose a name for the song (e.g. File-Name-Here .wav) and a location to save the exported song.


Following this there will be the Export Project window. This window displays all the export options that can be used to adjust the quality and precision of the exported song file.


File format

There are two options given in this window:

  1. *.wav or waveform audio format is usually the best choice for newer users because it can be read on most computers and media devices without conversion.
  2. *.ogg or ogg vorbis format is a preferred choice for those who are particular about sound quality, however this format is limited in what devices it can be played on.


This option is allows a person to adjust how many times the song will be sampled per second. The more times the song is sampled per second the more sensitive the exporter will be to changes in the song. In other words, if you have a lot of changes over a short amount of time you will want a much higher sample rate. In general this should be left as is, because if it is turned down too low the song with not progress properly and may make the final product sound distorted. On the other hand, if the sample rate is turned up too high the song file will become extremely large and take much longer when being processed by the exporting tool.


Bit rate refers to the amount/speed at which the song is processed by the device reading it. This option is important because it allows for choice of both quality and size of the song file. The higher the bit rate the better the quality of the music being read. However, a higher bit rate also means a larger song file. The following list gives comparable examples of bit rates.

Bit Rate Comparison
Bit rate Example
64 KBit/s > AM radio
128 KBit/s > FM radio
160 KBit/s =< Compressed MP3
192 KBit/s = Digital Audio Broadcast
256 KBit/s = High Quality MP3
320 KBit/s =< CD Quality


In simple terms this represents the way that the processor in the computer interacts with the program in terms of scientific notation or integer format while the song is being encoded. Choosing the 32 bit float will allow the computer to do a more accurate compilation of the song, however it requires more processing power to achieve this better standard of precision. Using the 16 bit integer will allow for faster processing, especially on older or underpowered computers. In general to achieve a better sounding song this setting should be set to 32 bit float.
