What “reviewed” means on this page
  • Format fit: whether the “what is this file?” description matches common real-world use of the extension, including category, typical MIME types, and aliases.
  • Opening paths: whether Windows / macOS / Linux steps read plausibly for current OS dialogs and default apps; we remove fantasy menus and unsafe shortcuts.
  • Security framing: whether risk notes match the extension class (for example executables vs plain data) and whether affiliate wording does not contradict the security section.
  • Sources and further reading: whether external links point to vendors, standards bodies, or other primary references where possible; we avoid inventing details we cannot ground.
  • Limits: this is clarity and safety-messaging QA, not a guarantee that every statement is exhaustive or that every binary you download is harmless.

Security notes

  • .LVP is an audio format (audio/vnd.lucent.voice), but treat it as untrusted input: opening malformed media files can sometimes trigger bugs in media parsers.
  • Prefer opening .LVP files with well-known, intended software (Avaya/Lucent Voice Player) rather than random “codec packs” or unknown converters from the web.
  • If a website asks you to install a browser extension or run an executable to “play .LVP,” avoid it unless you can verify it is the legitimate, expected software for this format.

Complex decoders and untrusted media

Image, audio, and video decoders are large software surfaces; issues are uncommon for everyday files but show up with crafted files from unknown sources. Keeping the OS and media apps updated matters most; scanning is reasonable extra caution for downloads you cannot vouch for.

Avast

Avast offers free and premium antivirus software that protects against viruses, malware, ransomware, and phishing. Scan files before opening them to ensure safety.

OS-specific troubleshooting

What is a .LVP file?

.LVP is an audio file format associated with Avaya/Lucent voice playback tools and is registered under the vendor media type audio/vnd.lucent.voice. On Linux desktops, file association may rely on the shared-mime-info database mapping extensions to MIME types. Because it is a vendor-specific audio type, many general-purpose media players may not recognize it by default.

Background

LVP files are most commonly encountered as voice recordings intended for playback with Avaya Voice Player, previously known as Lucent Voice Player. In practice, these files often appear in enterprise telephony/voice messaging workflows where recordings are exported or shared for review.

From a standards perspective, .lvp is associated with the vendor-specific MIME type audio/vnd.lucent.voice, which is listed in the IANA media type registry. On Linux, desktop environments typically determine what app to suggest by consulting the shared MIME database (shared-mime-info), which can map .lvp to this MIME type.

Because this format is vendor-specific, common consumer audio apps may fail to open it even though it is “audio.” When troubleshooting, it helps to confirm the file is truly an Avaya/Lucent Voice Player file (and not a different “.lvp” used by unrelated software).

Common MIME types: audio/vnd.lucent.voice

Common .LVP issues

The file opens as “unknown” or no app can open it

Many systems and media players do not include built-in support for vendor-specific audio/vnd.lucent.voice (.LVP) files.

  1. Open the file on Windows with Avaya Voice Player (formerly Lucent Voice Player).
  2. If your OS asks you to choose an app, select/browse to the Voice Player program rather than a generic audio player.

Linux desktop does not associate .lvp with an audio type

File associations may depend on the shared-mime-info database; if the mapping is missing/outdated, the desktop may not suggest the right app.

  1. Update your system’s shared MIME database (shared-mime-info) so extension-to-MIME mappings are current.
  2. Manually choose an application that supports Avaya/Lucent voice files, or open the file on Windows with Avaya Voice Player.

The file has the .LVP extension but does not play even in Voice Player

The file may be incomplete/corrupted, or it may not actually be an Avaya/Lucent Voice Player audio file despite the extension.

  1. Re-download or re-export the file from the original system to ensure the transfer completed correctly.
  2. Verify the source and context of the file (e.g., it came from an Avaya/Lucent voice system) before spending time troubleshooting playback.

FAQ

What program opens .LVP files?

They are commonly associated with Avaya Voice Player (formerly Lucent Voice Player), as described by file extension references for .lvp.

What is the MIME type for .LVP?

The vendor MIME type is audio/vnd.lucent.voice (listed by IANA and also referenced in technical MIME listings that associate it with .lvp).

Can I convert an .LVP by renaming it to .WAV or .MP3?

No. Renaming only changes the filename extension. You need software that can decode the .LVP audio and export/convert it properly.

Why won’t my phone play an .LVP file?

Because .LVP is a vendor-specific audio type, most mobile players don’t support it out of the box. Transfer it to a desktop (often Windows) and open it with Avaya/Lucent Voice Player-compatible software.
