Lossless and lossy compression format don't mean anything on preferred
form for modification. Some recorders do record mp3/ogg directly. And
some audio editors do edit mp3/ogg directly. And many of the authors of
the audio works don't know the difference between mp3 and wav and flac.
By ears, there's no difference between mp3 and wav, thus they may create
mp3 directly, or convert the wav to mp3 like put something into zip file
and then delete the useless wav.
So, for creative works, the source is hard to be defined by format. Not
like programs, we can easily know what is machine code and what is high
level language code in most situations. We can only ask the author of
the creative works to release their work honestly because in most
situation we can't distinguish the source and binary if the author is
lying. If the last format he has is wav, then he should release wav. If
the last format he has is mp3, then mp3.
The same thing also happens on images, like xcf/psd or png/jpg/gif or
whatever. But the author should release the true source he really has.
To require the author to use some listed formats for image source or
audio source is impracticable. And if we define ogg/mp3 is not source,
the games which have ogg/mp3 as data but cannot provide wav (may be
deleted by the author by nature) will be non-free due to DFSG#2.
