Chatter (move)/Effect/In battle/GenIV

Chatter inflicts damage and may the target. Pokémon with the Ability are not affected by this move. If the move has recorded audio from its field move functionality, that audio will play for the move's sound effect instead of Chatot's regular cry.

If Chatter has no audio data (as is the case for wild and NPC-owned Chatot), the chance of confusion is 1%. Otherwise, the chance of confusing the foe is determined by the volume of the recording.

Generally, the higher the volume of the recording is, the higher the chance of confusion. The recording is stored as a 1000-byte structure within the game as a 4-bit PCM recording. When a sound is recorded, 1984 8-bit of microphone input are taken at roughly 2000 samples per second. 16 zero bytes are appended onto the end of this recording to create a 2000 byte 8-bit PCM recording, which is then downsized to a 4-bit PCM recording via a translation table:

To pack two 4-bit samples into a byte, the first sample takes up the lower four bits and the second sample takes up the upper 4 bits. Now, depending on the value of the 16th byte in the 1000-byte 4-bit PCM recording (corresponding to the 31st and 32nd samples from the original), the chance of confusion is as follows:

The volume level roughly corresponding to the specific values are given in the table. Note that since the sample is near the beginning of the recording, it is not necessary to maintain a high volume throughout the recording.

The odds of confusion are not affected by, but are affected by.
