Texas Frog ID Help needed

["natureguyusa" natureguyusa]

Hi,

I am having difficulty identifying a frog sound recorded in the Texas
panhandle. The recording was made on May 12th. I added a link to a
sample sound file below. Among the Cricket Frogs, Woodhouse and Great
Plains Narrow-mouthed Toads is a lower pitched sound, similar to a Wood
or Mink Frog. I haven't been able to find an identification for it
anywhere. It maybe some type of Spadefoot that I haven't been able to
find an audio sample for. I am sure it is quite common, and I am hoping
someone here will be able to help.
