This page is the work of Sabine Cremer, DL1DBC. After exchanging lots of emails regarding RaspberryPi WSPR for her Medium Wave WSPR Monitor in JO41bi to try and get a USB soundcard that didn’t make the WSPR application crash, Sabine conduced some very extensive research into USB soundcards, which she has very kindly allowed me to reproduce here, along with her source code:
- USBSouncard_DL1DBC_alsatest.zip (Compile with option “-lasound”.)
The source code, written in C, and based on the ALSA API tests sound cards for number of channels and sample rates, etc. The code was used to find some of the data presented below. The code is entirely the work of Sabine Cremer, DL1DBC, but is again hosted here with kind permission.
Testing Conditions
BeagleBone Black: Ubuntu Precise 12.04.3 LTS; Openbox window manager; soundcard connected to DELOCK USB hub together with keyboard and mouse.
Raspberry Pi: Raspbian Wheezy; Openbox window manager, LXDE desktop; soundcard connected to upper root usb connector; keyboard and mouse connected to DELOCK USB hub
WSPR 4.0 r3015 compiled on Raspberry Pi and copied to BeagleBone Black
Results
Originally these results were sent in Excel format, so I have converted the spreadsheet into a table. Click for a bigger picture. WSPR version 4.0 r3015 used as test software.
- BBB: BeagleBone Black
- RPI: Raspberry Pi
