+      compression) between WAV file input and RADE encoder input during
+      this verification test
+
+## Baseline Loss (Step 1)
+
+Re-run with the current repository version before filling in this section.
+
+| Field | Value |
+|---|---|
+| Baseline loss | 0.079 |
+| 10% tolerance window | baseline ± 0.0079 |
+
+Command used:
+```
+$ pwd
+/home/ubuntu/freedv-integrations/build/src/backend/rade_build
+$ ./src/rade_tx_wav -f txfeatures.f32 ../rade_src/wav/all.wav tx.wav --v2

+Reproduction notes:
+```
+# (Assumes Level 1 done above.)
+# Use wpctl status to get correct target IDs for pw-record/pw-play.
+# Also, use pavucontrol or similar to adjust input and output to 50% volume.
+
+# In first terminal window
+$ pwd
+/home/ubuntu/freedv-integrations/build
+$ pw-record --target 74 --rate 8000 --channels 1 - | ./src/ka9q/freedv-ka9q --rx-features rxfeatures.f32 >/dev/null &
+
+# In another terminal
+$ pwd
+/home/ubuntu/freedv-integrations/build
+$ pw-play --target 73 tx.wav
+
+# Needed to flush rest of audio through pipewire
+$ sox -n silence.wav trim 0 10
+$ pw-play --target 73 silence.wav 
+$ killall pw-record
+ 
+# Back in first terminal window
+$ python3 src/backend/rade_build/radae/loss.py txfeatures.f32 rxfeatures.f32 --clip_start 100 --clip_end 300
