Hi, just discovered this repository as I was searching for something to convert seismic data into sound file, however trying it I noted that the data when converted lasts just a fraction of seconds and it's all broken. I used the miniseed file of an earthquake in Italy yesterday.
The clip lasts only 00.0141 seconds and it's all broken when viewed in Audacity.

So the first thing I did was to reduce the frequency to 200Hz which is the same frequency of the seismograph to get the "real-time" data of the quake. The lenght of the sound file increases however the data is still broken making just "random interference sounds" making it impossible to hear.

Converting the miniSeed file to a SAC file (another seismic data file) and using sac2wav library found in another project resolves the issues. It has the same timing issue, however this time decreasing the frequency to 200Hz creates a "real" sound of the earthquake and the waveform appearing in audacity is clearly visible.

I always work with miniSeed data so using your library might save me some time ahhahah thanks.
