2. select "Configure this screen";
3. Check ON "Show Status bar";

Status bar will appear at the bottom of the screen with 4 LEDs. if you touch it and drug up, it will expand.
In expanded window you will see original file format and bitrate and what it is converted to, something like:
MP3 320kbs -> OGG Quality: Optimal

To change quality you can do it separately for WiFi and Mobile connection.

In Muzecast Streamer Settings go to:
Settings->Streaming Options
First 2 items is settings for Streaming Quality for WiFi and Mobile connection.

Items are:

1. Original - will stream original file if it is: MP3, FLAC, OGG without any conversion;
2. Highest Quality - will stream in MP3 or OGG at variable bitrate averaging 256 kbs;
3. Near CD Quality - will stream in MP3 or OGG at variable bitrate averaging 192 kbs;
4. Optimal - will stream in MP3 or OGG at variable bitrate averaging 160 kbs;
5. Good - will stream in MP3 or OGG at variable bitrate averaging 128 kbs;
6. FM Radio - will stream in MP3 or OGG at variable bitrate averaging 96 kbs;


3rd item is to select if you want to stream in variable bitrate to constant. Constant bitrate while streaming in MP3 will help with SEEK to be more precise. For OGG it is better to keep it variable.
