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 44.1kHz. If you see this

message, the simplest approach is to re-sample the audio at 44.1kHz 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 in-

serted 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
