Capitalizing KBPS will be confusing.

In data communications a Kilobit is one thousand bits. It is used to measure the amount of data transferred per second. Kilobits per second is shortened to kb/s, Kbps or kbps (as opposed to KBps, which is Kilobytes per second. Note the capitalization.) The lowercase b is commonly used to denote bits, while the uppercase B is used for bytes. ^source

In order not to misunderstand YouTube's audio needs, quotes from support.google.com

Encoding specifications for music videos. The media files you deliver to YouTube for music videos must conform to these specifications. HERE

Although it is not recommended, YouTube accepts compressed audio. YouTube transcodes from the delivered format; audio quality is much better when transcoded from a lossless format compared to re-compressing a lossy audio format.

If you must deliver compressed audio, use these specifications:

• Codec: AAC-LC
• Sample Rate: 44.1Khz
• Bit Rate: 320kbps or higher for 2 channels (higher is always better; 256 kbps acceptable)
• Channels: 2 (stereo)
