+"""Decodes Argonaut ASF music (v2.1, 4-bit ADPCM) like the game's asfcodec.adl.
 
-Nachgebaut aus der Disassembly von asfcodec.adl (Routinen 0x26e01969 / 0x26e01ca1):
+Reimplemented from the disassembly of asfcodec.adl (routines 0x26e01969 / 0x26e01ca1):
   Filter 0:  s = s1 + (n << shift)
-  Filter 1:  s = 2*s1 - s2 + (n << shift)      (+ Übertrag aus 'adc', s. u.)
-  - kein Clipping; Ausgabe wird als 16 Bit gespeichert (Überlauf = Wrap)
-  - s1 läuft innerhalb eines Blocks ungekürzt im Register weiter,
-    am Blockanfang wird es aus dem 16-Bit-Puffer gelesen
-  - s2 wird immer aus dem 16-Bit-Puffer gelesen
-Aufruf: asf2wav.py eingabe.asf ausgabe.wav
+  Filter 1:  s = 2*s1 - s2 + (n << shift)      (+ carry from 'adc', see below)
+  - no clipping; output is stored as 16 bit (overflow = wrap)
+  - within a block s1 carries on untruncated in the register,
+    at the start of a block it is read from the 16-bit buffer
+  - s2 is always read from the 16-bit buffer
+Usage: asf2wav.py input.asf output.wav
