MP3 vs WAV: quality, size, and the right formatUse WAV for an editable or lossless PCM working file; use MP3 when small size and broad playback matter more.MP3 vs FLAC: lossy listening copy or lossless archiveFLAC preserves the decoded audio exactly; MP3 discards information to produce a smaller file.WAV vs FLAC: uncompressed workflow or lossless storageBoth can preserve lossless audio. FLAC saves storage; PCM WAV is simpler for many editing workflows.MP3 vs AAC: compatibility, efficiency, and qualityAAC is generally more efficient at comparable bitrates, while MP3 remains easier to play on old hardware and legacy software.MP3 vs OGG Vorbis: compatibility or open-format workflowMP3 wins on universal playback; OGG Vorbis is useful in open web, game, and software workflows.M4A vs MP3: what the extension really meansM4A is a container that commonly holds AAC audio; MP3 is both a codec and a familiar file format.AAC vs M4A: codec versus containerAAC describes encoded audio; M4A usually describes an MP4-family container that can carry AAC plus tags and artwork.FLAC vs ALAC: two lossless audio codecsFLAC and ALAC both preserve decoded audio; the practical choice is device and library compatibility.WAV vs AIFF: PCM containers for productionWAV and AIFF commonly store uncompressed PCM. Choose the format your recording or editing software handles most consistently.CBR vs VBR audio: fixed rate or adaptive qualityCBR targets one bitrate throughout; VBR spends more bits on complex passages and fewer on simple ones.128 vs 320 kbps MP3: size and audible tradeoffs320 kbps allocates 2.5 times as many bits per second as 128 kbps, but it cannot restore information missing from the source.192 vs 320 kbps MP3: when the extra size matters192 kbps is a practical size-quality balance; 320 kbps reduces compression pressure but produces files about two-thirds larger.Mono vs stereo audio: channels and file sizeMono carries one channel; stereo carries two. Stereo can preserve spatial separation, while mono is often sufficient for speech.Lossy vs lossless audio compressionLossless codecs reconstruct the source samples exactly; lossy codecs discard selected information to save more space.44.1 kHz vs 48 kHz sample rate44.1 kHz is standard for music distribution; 48 kHz is standard in video and many production workflows.Bitrate vs sample rate: two different audio measurementsSample rate describes measurements per second in sampled audio; bitrate describes encoded data per second.Audio codec vs container: why extensions can misleadA codec compresses audio; a container packages streams, timing, and metadata. One container may hold several codecs.
