+
+## Character dedeplication
+### If any of the following repeat 5 or more times, they were replaced with 4:
+'あ'  'い'  'う'  'え'  'お','ぁ'  'ぃ'  'ぅ'  'ぇ'  'ぉ'  'ん'
+
+For example:「ふにゃあああああああ」->「ふにゃああああ」
+
+Reasoning: Some audio contains elongated vowel sounds that are long enough to justify 4 characters
+
+### If any of the following repeat 4 or more times, they were replaced with 3:
+'～'  'ー'
+
+For example:「きゃわーーーー！？」->「きゃわーーー！？」
+
+Reasoning: Some audio contains elongated vowel sounds that are long enough to justify 4 characters but 3 looks better for 長音符 in my opinion
+
+### If any of the following repeat 3 or more times, they were replaced with 2:
+'！'  '？'  'っ'  '！？'
+
+For example:「は！？！？！？」->「！？！？」
+
+Reasoning: These are characters that shouldn't repeat much.
+
+### If any of the following repeat 2 or more times, they were replaced with 1:
+'…'
+
+For example:「それは……はい」->「それは…はい」
+
+## Other filtering
+I got rid of trailing「…」
+
+For example:「それは…」->「それは」 and 「…そうです」->「そうです」
+
+I removed「…」that appears before punctuation
+
+For example:「…？」->「？」
+
+## Reflection
+* I should consider katakana characters, for some reason I forgot.
+* I think I'll limit「！？」to no repetitions next time
+* There are 192 transcriptions that start with「。」due to string replacements. I should remove these.
+* I should further remove low quality transcriptions who's only characters are: 'ー'  'っ'  'ッ'  '…'  '！'  '？' etc.
+* Open to feedback
