The standard programming sequence for uRec 384k recorders requires the use of an Android phone or tablet. It is not possible to use another operating system to run the application.
The application must first be downloaded and installed.
The application must be downloaded and installed manually ( AVAILABLE HERE ) and is NOT available in the Google Play Store.
Once installed and authorised to run on your device, you can see the sequence of operations in this video. During installation and/or during the first run, some security messages may appear and you need to give the required permissions:
For correct programming, the recorder must contain the memory card that will later be used for audio recordings.
The application will write a configuration file called ultramic384.xml to the card.
On first successful use, the file is renamed ultramic384.old and is not altered in any other way.
Manual programming is also possible by editing the ultramic384.xml file with a text editor.
The following example shows the contents of the file and how to modify it to suit your needs.
The following is an example of a file. This is the programming for a repeated cyclic recording. Below are notes and explanations of the fields.

1.3 this is the header or header of the file and allows the unit to recognise the correctness of the following
opens the actual configuration part
2 sets the sampling frequency to 192kHz
0 declares not to use a trigger
5m declares to obtain files with a maximum size of 5 m, i.e. minutes. if files are larger, depending on the following parameters, they are broken up into maximum blocks of 5 minutes. it is an easily editable parameter.
devicename is the name of the recorder, which will also be used in the naming of generated files
1-60-30 parameters indicating end of sampling or trigger recording conditions. In our case they should not be used and should be left as they are.
2022-09-20 this is the date on which sampling is to begin. It MUST be a date equal to or later than the date specified in the parameter below . It can also be an adjusted date in the days following today.
indicates the end of the recorder’s basic standard parameters
this tag opens the section in which we indicate the type of sampling and also indicates that we want recording in REPEAT mode, i.e. a duty cycle in which we indicate a recording period and a subsequent pause/stand-by period.
19:09 this is the time at which we want to start sampling. it must be later than the time indicated below in . it can be any time in the future and is linked to what is indicated in .
00:05 here we indicate how long our recording lasts, in minutes (hh:mm).
00:05 here we indicate how long our break lasts, in minutes (hh:mm).
close the space dedicated to sampling parameters.
2022-09-20T19:06:32 here we set the date and time of the moment when we will supply power to the system. Basically, the system will read this date and time and use it as the start time. This means, for example, that we will be able to set this date and time in the future, one hour from now, save the configuration file, take out the mSD card, insert it into the recorder WITHOUT batteries, wait for the exact time that we have indicated in the parameter, and at that instant insert the batteries into the unit. This time must be a time before and in , otherwise sampling will not start.
this tag closes the configuration space and is a mandatory tag.
