Converting WAVE to FLV (Flash Video) embeds audio into Adobe's Flash Video container, historically used for web-based media streaming. FLV supported MP3 and AAC audio codecs alongside video, making it the backbone of early YouTube, Hulu, and most 2005-2015 era web video players.
WAVE files (.wave or .wav) contain uncompressed audio that must be re-encoded to MP3 or AAC to fit within the FLV container — FLV does not support raw PCM audio. This conversion was once essential for web publishing but is now largely obsolete due to Flash Player's discontinuation.
Some legacy content management systems, e-learning platforms, and archival web players still use FLV as their media format. If you maintain or update content for these older systems, converting WAVE audio to FLV may be necessary to keep the platform functioning.
Historical web archives and digital preservation projects may also need FLV files created from original WAVE sources to maintain format-accurate representations of early web media content.
FFmpeg decodes WAVE PCM and re-encodes to MP3 (libmp3lame) or AAC (aac encoder) within an FLV container. The FLV format supports MP3 at up to 320 kbps and AAC-LC at up to 576 kbps. Audio-only FLV files contain no video stream — just the audio with FLV container headers. The FLV muxer writes audio tag headers with timestamp, codec ID, sample rate, and channel information for each audio packet.
Quality depends on the chosen audio codec and bitrate. MP3 at 192-320 kbps in FLV provides good quality. AAC at 128-256 kbps provides better quality at equivalent bitrates. Both represent lossy compression from the uncompressed WAVE source, with typical perceptual transparency achieved at 128+ kbps for AAC or 192+ kbps for MP3.

WAVE to FLV serves legacy web platforms still dependent on Flash infrastructure. For new projects, use MP4 or WebM instead.
