# `Mojentic.Realtime.Codec`
[🔗](https://github.com/svetzal/mojentic-ex/blob/v1.5.0/lib/mojentic/realtime/codec.ex#L1)

Audio codec helpers for the realtime subsystem.

Realtime sends and receives audio as base64-encoded PCM16
(little-endian 16-bit signed mono, 24 kHz by default). These helpers
convert between the wire format and Elixir binaries of raw PCM bytes
so consumer code never touches base64.

# `decode_base64_pcm16`

Decode a base64 string into a binary of little-endian 16-bit PCM samples.

Returns the raw binary; pattern-match `<<sample::little-16-signed, rest::binary>>`
to consume samples or use `:binary.bin_to_list/2` for arrays.

# `encode_base64_pcm16`

Encode raw PCM16 bytes (or a list of int16 samples) into a base64 string.
