Corrupt file descriptions and diagnoses
Corrupt file: This MP3 contains invalid
frames.
This MP3 contains frames which do not conform strictly to the official MP3 specifica
-
tion. 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.
This is a rare message and you should not see this. Do notify us if you see it and please
send us the file that caused the message to appear so we can fix the problem.
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 sup-
port 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 mes
-
sage, 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
.
