I am trying to convert files at 128 kbps low compression to at least 256 kbps to use on special sound/light equipment but am coming up empty handed. I try different formats but am not successful with this process. If you can help me with this that would be awesome. Thanks in advance. 
When asking a question, please read the pink panel at the top of the page and give us your version of Audacity and Windows. We usually need to know that.
You also donāt say what format you want to write. Assuming you want to write MP3, the first step is to install LAME following Audacity Manual.
The File > Export Audioā¦, choose āMP3 Filesā, then click the āOptionsā¦ā button to choose 256 kbps.
Please be aware that MP3 is always lossy encoding. Even if you increase the bit rate, you are just making the files sound worse.

I have the latest version and it is a .wav file. Iām doing special hypnotherapy sessions redirected through special sound/light eequipment for super powerful results. The sound needs a low compression at least 258 kbps in order to control the lights
Please read the pink panel at the top of the page. We like to know all three Audacity version numbers or we donāt know what you have.
We canāt help you unless you say what format you want the outcome file to be in. What does the manual for this equipment say you need, exactly?
We have told you how to make MP3 at 256 kbps. You can still export an MP3 even if you have a WAV file to begin with.
WAV is not (usually) size-compressed.
A mono 16-bit WAV at 44100 Hz is 705 kbps. Is that you want? If so, Tracks > Stereo Track to Mono (if you have a stereo track) then choose 44100 Hz bottom left of Audacity. Then File > Export Audioā¦ . Choose WAV (Microsoft) signed 16-bit PCM, Save.

Thanks, Iāll try that. I went through the tutorial last night but did not get the results I was looking for. Itās a hit and miss thing.
