Where 200 KB matters

A 204,800-byte file: twice the default body limit of most API frameworks, and a common cap for photo and signature uploads on application forms. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Express body parsers	100 KB by default	Rejected with 413 unless the limit is raised.
Amazon DynamoDB items	400 KB per item	200 KB fits, even after base64 encoding takes it to about 273 KB.
Azure Service Bus, Standard tier	256 KB per message	Fits as raw bytes, but not once base64-encoded.

Testing notes for MP3

Duration is not stored in a header. Players estimate it from bit rate and file size, which goes wrong for variable-bit-rate files that lack a Xing header.
A large ID3 tag with artwork can push the first audio frame far into the file, confusing naive sniffers.
