[PROBLEM] Measurement Sweep - incomplete play

[timedelay]

Tim,
Hi. A little background. Running REW measurement sweep to record room sound behavior. I play the wav file using moOde audio player. Hardware are raspberry pi, Allo Piano, Kali. MPD output at 16 bit PCM 48 Hz. This is just for info. I do not not think it is hardware related.
I play the wav file first through Airplay from my Mac. All is fine. I could hear the first time code, then the sweep, and finally another time code.
But when I copy the file onto a USB drive and connect the drive to Pi through USB port on the Pi, then play it in moOde audio player in Chrome web browser, I hear the first time code, the sweep, and no second time code. Tried several ways through a PC, and it is the same. Any insight?
Airplay and MPD are different ways to render the wav file?
The measurement  sweep is generated by REW, 2 channel, time codes in the left channel, 16 bits, 48 Hz PCM, wav file.

I've packed up most everything but my Linux laptop in preparation for a move.

However, I just tried following in your footsteps using REW V5.19 on the laptop with Oracle jre1.8.0_291 to generate a L+R-channel measurement sweep file running from 50Hz to 1000Hz adding a timing reference signal on L-channel and setting bitwidth / sample rate = 16bit/48kHz.

Examining the resulting file in Audacity I see a timing reference pulse on L-channel at time=0 but no timing reference pulse at the end. That's what I hear on playback as well---a brief beginning pip on the left channel followed by a frequency sweep on both channels and no trailing pip.

How did you use REW to generate a sweep file with timing reference signals at both beginning and end?

Kent

Hey. Thanks for helping out.

I load the file into Audacity:
   

REW v5.20 created the 2nd time code I think for the impulse response.

I am going to load the wav file into my original post to see if anyone can reproduce it.

I am also doing offline measurement because I can not connect the REW computer to Raspberry Pi to do online measurement.
