Corrupt file: This MP3 contains invalid frames.
This MP3 contains frames which do not conform strictly to the official MP3 specification. Scratch LIVE can not be
certain that this file will play back 100% accurately.
Corrupt file: This file contains corrupt frames that
may result in audible glitches.
This file contains two or more contiguous corrupt frames. Since corrupt frames are replaced with silence, this could
result in what might sound like an audio glitch.
Corrupt file: This file has been split. You should check
the beginning for audio glitches.
The first MPEG audio frame in this file refers to audio that should be present before it but is not. This is usually the
result of incorrect MP3 editing. Since a corrupt frame is replaced with silence and most songs start with silence, the
resulting silence might not be noticeable. All the same, listen to the beginning of the song, just to be sure.
Corrupt file: This MP3 contains frames with corrupt
data.
Decoding of an MPEG audio frame failed. This means that the frame contained invalid data. As usual with corrupt
frames, this frame will be played as silence.
Corrupt file: This MP3 lost syncronization between
the frame index and the frames.
Scratch LIVE is reading an old overview of an MP3 that has been edited in a 3rd party editing program. Re-building
the overviews for the affected files usually corrects this error.
Corrupt file: This MP3 is completely invalid and is not
playable.
Self explanatory. Possible causes are disk bad sectors, file system corruption, wrong file types, wrong file extensions,
etc
Corrupt file: This file contains invalid audio data.
Scratch LIVE encountered a lot of invalid data while looking for audio in this file. This message alerts you to the fact
that the file you're trying to play contains corrupt data. This may, or may not, affect playback.
Corrupt file: This MP3 contains no valid frames.
No audio could be found in this file, which means it is completely unplayable as far as Scratch LIVE is concerned.
Please make sure this really is an audio file.
Unsupported file: This MP3 contains multiple layers.
While scanning this file, Scratch LIVE found frames belonging to multiple MPEG layers. Scratch LIVE does not support
MP3s that contain frames from multiple layers – some frames may be output as silence.
Unsupported file : This file is more than 2GB in size.
Self explanatory. At the moment, Scratch LIVE does not support files that are 2GB in size (or larger).
Unsupported file : This file has data blocks greater
than 2GB in size.
This file contains chunks of data that are larger than 2GB. Scratch LIVE does not support files that are more than 2GB
in size.
Corrupt file: This WAV contains no valid chunks.
This WAV file contains no recognizable WAV data. It is quite possible that this might not be a WAV file.
Unsupported file: This file's data is not in PCM
format.
WAV files can contain data in several formats. Scratch LIVE only supports WAV files that contain data in the PCM
format.
Unsupported file: This file has a sampling rate greater
than 48kHz.
Scratch LIVE does not support sampling rates greater than 48 kHz. If you see this message, the simplest approach is
to re-sample the audio at 48 kHz and re-save the file.
Unsupported file: This file uses more than 24 bits per
sample
Scratch LIVE supports a maximum of 24 bits per sample of audio data.
Corrupt file: This WAV is incomplete.
Scratch LIVE expected more data in the file, but found none. This could be because the file was incorrectly truncated
or because the data in the file is corrupt, causing Scratch LIVE to incorrectly estimate the amount of data present in
the file.
Corrupt file: This file contains corrupt blocks.
This file contains blocks of data that report their size to be zero. This message was inserted to identify files that might
cause lockups on previous versions of Scratch LIVE.
Corrupt file: This song contains no audio data.
Scratch LIVE could not find any audio in this file. Please check to make sure this file contains audio in a format that
Scratch LIVE supports.
Corrupt file: This song contains invalid samples.
This file contains samples of audio that are too small to represent accurately and will therefore be truncated to zero.
This should not result in any audible audio artifacts, but could cause audio dropouts on earlier versions of Scratch
LIVE.
