Settings

Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.
Adjust the audio volume by selecting a number of decibels. For example, -10 dB decreases the volume by 10 decibels.

asf

ASF (Advanced Systems Format) is a proprietary digital media container developed by Microsoft to support streaming over networks. Introduced in 1996, it was originally called Active Streaming Format and later renamed to Advanced Streaming Format before receiving its current name. ASF serves as the underlying container for Windows Media Audio (WMA) and Windows Media Video (WMV) content, though it can accommodate data from any codec. The format was architected with network delivery in mind, incorporating features such as forward error correction, scalable bit rate support, and the ability to seek within streams without downloading the entire file. ASF files include a header object containing metadata, a data object holding the actual media content, and optional index objects that enable efficient random access. One key advantage is built-in support for digital rights management, which made ASF a popular choice for commercial content distribution during the early days of online media. The container handles multiple synchronized streams, including video, audio, script commands, and metadata markers. While ASF has been largely superseded by more modern containers in many use cases, it remains relevant in legacy Windows media ecosystems and enterprise environments that rely on Windows Media Services infrastructure.

wv

WavPack is an open-source audio codec created by David Bryant, with version 1.0 released on August 15, 1998. What sets WavPack apart is its unique hybrid mode: the encoder can simultaneously produce a compact lossy file and a separate correction file that, when combined, reconstruct the original PCM stream bit-for-bit. Users who need portability carry just the lossy file; those who want archival quality keep both. The codec handles PCM audio from 8-bit to 32-bit integer and 32-bit floating point, with sample rates up to 768 kHz — specifications broad enough for DSD content, which WavPack 5 added support for. Compression ratios in pure lossless mode typically reach 40 to 55 percent of the original size, competitive with FLAC and often slightly better on certain material. Multicore encoding in later versions dramatically speeds up processing on modern hardware. The open-source library ships under a BSD license and has been integrated into foobar2000, VLC, FFmpeg, and numerous other tools. WavPack also supports rich metadata through APEv2 tags, embedded cue sheets, and ReplayGain values, covering the organizational needs of even the most meticulous music library.

Frequently Asked Questions

Why convert ASF to WV?

ASF has limited cross-platform support and poor compatibility outside Windows. Converting to WV gives you lossless compression with a hybrid mode and makes your content more accessible.

How do I open a WV file?

You can play WV using foobar2000, VLC, or WavPack's own command-line tools. No special configuration is usually required.

Does converting ASF to WV keep only the audio?

Yes — when you convert a video format to WV, the converter extracts the audio track and discards the video stream entirely.

Does the conversion work on mobile?

It does. Convertio.tools works in any modern mobile browser — upload your ASF, convert to WV, and download directly on your phone.

Can I adjust the output bitrate?

Yes — set the desired bitrate before converting. Lower bitrates produce smaller files, while higher bitrates preserve more audio detail.
