Ogg is a lossy formar, Wav is not. They are not compatible.
The question should be “Flac or Wav?” And the answer is Flac, unless you need some kind of old compatibility.
what does lossy mean and why flac
Basically if you rip a CD to WAV, you’re getting a 1:1 rip of the audio that takes up the same amount of space. A 75 minute CD will take up 650mb as a WAV rip.
Lossy compression means that some data is basically thrown out to improve the compression ratio. It might sound the same to most people, but something is missing, and you can’t reconstruct the original anymore. You can easily get a 10:1 compression ratio with near-CD quality audio. Ogg is a lossy format with high compression and good sound quality.
Lossless compression means that the resulting file is compressed in such a way that all of the data is still there. You can convert the compressed file back to the exact original file. The compression here is closer to 4:1 generally. FLAC is lossless and the sound is exactly the same as the source.
Edit: Check the replies to my post for corrections and clarifications.
I’ll answer your question and more.
Lossless quality: The highest quality you can practically get, where it’s as close to a 1:1 recreation from the studio as reasonably possible.
Lossy quality: The audio is compressed in a manner where you get the majority of the sound, but slight, fine details are lost to lighten up on file size. Heavy compression can greatly alter overall sound quality, but it’s not the early 2000s anymore, we don’t need to compress music that hard to get an album or two to fit on a 128 mb card.
.wav: Lossless, uncompressed file. Full quality, full file size.
.flac: Lossless quality, but with some compression, to minmax file size to audio quality.
.mp3: Lossy compressed. Small file size with reduced audio quality.
.ogg: Lossy compressed. Basically just an alternative to the .mp3 standard.
Your answer is correct but I am going to needlessly nitpick: Actually, OGG is just the name of the container format. The audio stream inside a
.oggfile is usually using a format called Vorbis. However,.flacfiles also use an OGG container afaik, they just have different file format convention. Same goes for the newer Opus audio format which usually uses.opusdespite also being packaged in an OGG container. In any case, it wouldn’t be entirely wrong to name a FLAC or Opus file.ogg.Side note: Opus is the future but sadly not yet widely compatible outside browsers. FLAC is great and more widely established but also has its support deficits. MP3 and WAV are still the most widely compatible formats sadly.
Lossy means that the compression gets rid of the finer points of data to save on space that usually wouldn’t bee too noticeable in the music. Lossless keeps all the data
Lossy means that data is lost on encoding, so the original quality of the recording will be compromised in some fashion.
FLAC is superior to WAV because it’s still lossless but compressed so the files take up less space.
I thought ogg had multiple formats, some of which weren’t lossy.

Depends on what counts as “better”.
Better quality? WAV, since it’s lossless.
Better efficiency? OGG (well, Vorbis) since it compresses pretty well, but you’ll still get a (minor) loss in quality.
That said, both of those formats are old news and should only be used if you have weird, specific compatibility needs. For lossy compression, OGG/Vorbis has been succeeded by Opus; it’s what YouTube uses, compresses fantastically, and is supported by damn near everything. For lossless, FLAC (Free Lossless Audio Codec) is still the gold standard: you can reduce file sizes by as much as 60% with literally zero loss in quality. If you can, use one of those.
For what? wav is your lossless container. Pretty much universally recognized. Think of it like RAW for photos. ogg is lossy and more appropriate for most use cases, but is not universally recognized and not available on all devices.
Not a good comparison. Wav is lossless, ogg is lossy. If it’s for general listening, ogg. If it’s for storage or reconversion, wav. And let’s be honest, in most cases you’d want to convert wav to flac if you go that route.
.wav files store volume levels (typically, but often higher) as a 16bit value 44100 times a second (again, typically, but often higher). This allows frequencies up to 22050Hz to be stored without losses. A lot of this is useless information, because most people don’t hear anything above 16kHz, which only gets worse with age. Other parts of this might be useless information because of complex low frequency interaction with the inner ear which occlude some higher frequencies (psychoacoustics was a long time ago, can’t explain it in detail). .ogg and .mp3 filetypes, among others, use that to simply cut frequencies that (probably) aren’t heard. This process saves a lot of data, but results in lower resolution, especially in the higher frequencies (look up comparisons for 128kBit/s vs 320kBit/s MP3, you’ll hear the difference immediately on pretty much anything other than phone speakers.)
If file size is an issue, .ogg is great, if quality is the most important, go for .flac, as flac files also don’t loose any quality while having file sizes between the two, though compatibility might be a problem on older systems.
None, FLAC is
wav
