Verdict Safe
Is soft_
This DLL appears to be the widely used OpenAL Soft audio library, with no detections from 75 engines and thousands of submitters over nearly six years.
Read the whole reasonShow less
Strong evidence · Widely seen for a long time, and nothing harmful found.
This library is consistent with the common OpenAL Soft audio component and can be kept when it ships with a trusted application. Replace it only from the original software source if in doubt.

We found nothing harmful in this file.
Use it only as part of a program you got from the developer's own website.
Keep your antivirus and Windows updates switched on.

Why we think so
2 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Its exported audio functions match the OpenAL Soft library bundled with many games, and nearly 3,000 distinct sources have submitted it since 2020. Sandbox activity showed no injection or other high-risk behaviour.
No engine, including all major antivirus engines such as Kaspersky, ESET and BitDefender, detected the file. It has been seen by 2,933 distinct submitters since November 2020, which fits a common redistributable component. The exported functions observed during execution are OpenAL Soft audio APIs, consistent with the file name. Matching YARA rules were only generic anti-debug and compiler patterns, and the file is not packed. No complete contacted-host reputation result was available.
What We Detected
None of the 71 antivirus engines that checked it flagged this 64-bit DLL. It exports OpenAL Soft audio functions and has been submitted by 2,933 distinct sources since 2020. Only generic community YARA rules matched (debugger checks, TLS callbacks), which ordinary software also triggers. The file is not packed.
Threat Behavior
The sandbox runs loaded the library through rundll32 calling its audio exports. No process injection target, persistence or registry changes were recorded. One direct IP contact was seen, but no host-reputation result is available for it. Some technique labels were mapped without supporting artefacts and are typical of clean software.
What To Do Now
If this DLL came with a game or audio application, it is expected to be there. Obtain it only from the original application or the official OpenAL Soft project, and keep your security software enabled.
Where this verdict could be wrong3 caveats
- The library is unsigned, so its publisher cannot be confirmed from a signature.
- A sandbox run recorded one direct IP contact whose reputation was not checked.
- Two community annotations relay a third-party automated 'likely malicious' verdict based on generic anti-debug and rundll32 tags, which no antivirus engine corroborates.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 71 antivirus engines that checked it flagged the file.
- Seen by nearly 3,000 distinct sources over almost six years.
- Exported functions match the OpenAL Soft audio library.
- Not packed; only generic YARA rules matched.
- The DLL is not digitally signed.
- One direct IP connection was observed without a completed reputation check.

VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
