I am reading a .wav file that has been collected using an hydrophone (underwater acoustics instrument). So far I have downloaded the two packages: tuneR and Seewave. I use readWave in tuneR:
> audio_file <-readWave("icListen_HF_test.wav")
> audio_file
Wave Object
Number of Samples: 15360000
Duration (seconds): 60
Samplingrate (Hertz): 256000
Channels (Mono/Stereo): Mono
PCM (integer format): TRUE
Bit (8/16/24/32/64): 24
This is good, but for calculations purposes on the data, I need to access more information that's stored in this .wav file. According to the OceanSonics manual page 12 (see Table 3.3), there is a data chunk called ICMT, in which there are three values I need to get:
- Count At Full Scale Voltage,
- Full Scale Voltage, and
- Hydrophone Sensitivity.
How do I access those? I can't seem to find the function for it in those two packages I am using so far.
Thanks in advance for your help!
