I am attempting to read a files audio length in Java using the following code:

return AudioFileIO.read(new File(audio)).getAudioHeader().getTrackLength() * 1000;

This works and gives me (roughly) the length of the audio file, but leaves an inputstream open, meaning that later on I cant delete the files, atleast not during runtime. This is problematic because Im using temporary files here and the directory needs to be cleared.

This is the output I get in my console:

Mai 06, 2023 10:30:13 PM org.jaudiotagger.tag.id3.AbstractID3v2Frame readIdentifier
WARNING: tmp0.mp3:No space to find another frame:
Mai 06, 2023 10:30:13 PM org.jaudiotagger.tag.id3.ID3v24Tag readFrames
WARNING: tmp0.mp3:Invalid Frame:tmp0.mp3:No space to find another frame
Mai 06, 2023 10:30:13 PM org.jaudiotagger.audio.mp3.MP3File readV2Tag
SEVERE: Could not invoke DirectBuffer method - illegal access`

This is the files metadata, according to (https://www.checkfiletype.com):

File Size   36 kB
File Type   MP3
File Type Extension mp3
MIME Type   audio/mpeg
ID3 Size    45
MPEG Audio Version  2
Audio Layer 3
Audio Bitrate   128 kbps
Sample Rate 24000
Channel Mode    Single Channel
MS Stereo   Off
Intensity Stereo    Off
Copyright Flag  False
Original Media  True
Emphasis    None
Encoder Settings    Lavf58.76.100
Duration    2.30 s (approx)

I cant entirely seem to understand what the problem is thats making it throw that warning. Is the metadata faulty? If so, what can I do to fix it? Im getting the .mp3 through an API. Is there a different class I could use? The AudioSystem/AudioInputStream classes didnt work either and threw an error, saying the file type is unsupported.

Thanks in advance!

The problem was fixed by increasing the maven depdendency from 2.2.5 to version 3.0.1:

<dependency>
    <groupId>net.jthink</groupId>
    <artifactId>jaudiotagger</artifactId>
    <version>3.0.1</version>
</dependency>
