Save as MP3 when the file has to open anywhere, WAV when it goes into an editor, and WebM or OGG when you want the smaller file at good voice quality. In Audio Recorder – Voice Recorder all four come from the same take, so you can export one recording in several formats without recording it again.
The format choice lives under Settings → Save as. WebM is the default. The setting only affects the file you get when you press Download or Share; the copy inside the popup's library remains the same no matter what you pick.
What each format really is
People often treat these as four "qualities". They are really two codecs in three containers, plus one uncompressed option.
| Save as | Codec inside | Compression | Bitrate follows Quality? | Typical use |
|---|---|---|---|---|
| WebM | Opus | Lossy | Yego | Kureba mu Mbuga, kohereza kuri interineti, gufata utubiko duto cyane |
| OGG | Opus | Lossy | Yego | Amajwi ameze nka WebM ariko mu gikoresho bamwe mu bakinnyi bakunda |
| MP3 | MP3 (LAME encoder, ihari mu gikoresho) | Lossy | Yego | Radiyo z’imodoka zakera, porogaramu z’ibiro, umuntu wese usaba “MP3” |
| WAV | 16-bit PCM | Oya | Oya | Abatunganya amajwi ku mashini, ibikoresho byo kwandika ibyo wavuze, kubika igitabo cy’icyitegererezo |
WebM na OGG byombi birimo amajwi ya Opus ameze kimwe; itandukaniro ni mu gikoresho gusa. Niba umukinnyi umwe yanze, gerageza undi mbere yo kwemera ko amajwi yavubitswe ari yaboze.
Uko kohereza bikorwa inyuma y’akabuto
Mugihe urimo gufata amajwi, iyi nyongera yandika amajwi ya Opus mu gikoresho cya WebM muri porogaramu y’ububiko bw’imbere muri browser, igice kimwe cy'isegonda rimwe igihe kimwe. Uwo murongo wabitswe ni wo soko kuri buri kohereza:
- WebM, idakurutse — udupaki tw'umwimerere twa Opus dusubiye gupakishwa hamwe n'igihe gikwiye kugirango abafatabuguzi bashobore gushakisha. Nta kongera guhindura kode, bityo nta kintu na kimwe kibura.
- WAV — ifatwa rijyanwa muri 16-bit PCM kuri 48 kHz kandi rikorwa uko riri. Nta kintu kibura kuva kuri aka kanya, ariko ntirishobora kongera hamwe n'amakuru Opus idafite.
- OGG, WebM yakuweho ibintu bimwe — byashyizwe muri kode hanyuma byongeye guhindurwa muri Opus ku muvuduko wa Quality uriho ubu.
- MP3 — byashyizwe muri kode hanyuma byongeye guhindurwa hifashishijwe LAME encoder iri mu gikoresho ku muvuduko wa Quality uriho ubu.
Ikintu cya nyuma kirakenewe: kohereza muri MP3 ni igikorwa cya kabiri gitakaza ubuziranenge. Ku rwego rwo hejuru cyangwa rwiza cyane, biragoye kubyumva mu magambo, ariko niba ijwi rizahindurwa, rikazacungwa bundi bushya n’urubuga rwa videwo, hanyuma rikumvikwe kuri telefoni, intambwe zose zitakaza ubuziranenge zibara hamwe. Kuri urwo rugendo, kohereza muri WAV rimwe hanyuma ugasiga igikoresho cya nyuma ari cyo gikora compression yonyine.
Guhitamo hashingiwe ku buryo bwo kohereza
Koherereza umuntu
MP3. Ni format ishobora gutera igisubizo cyo "ntibishobora gufungura iyi file" gike cyane. Ijwi ry'amasegonda icumi muri High riba riri hafi ya 9.6 MB (128 kbps ÷ 8 = 16 kB ku isegonda × 600 s), bihagije kuri porogaramu nyinshi za email na chat.
Guhindura mu software yo ku desktop y’amajwi
WAV. Abahindura amajwi bakoresha PCM nta kinjira mu gukuramo code, kandi wirinda gushyira encoding ya MP3 ku byo export software ikora nyuma. Tegereza amafile manini: 48 kHz, 16-bit mono WAV ni 96 kB ku isegonda, hafi 346 MB ku isaha. Inyandiko y'ubunini bwa file ifite urutonde rwuzuye.
Gushyira kuri website cyangwa kubika archive
WebM. Ni ifoto y'umwimerere nta encoding y'inyongera, ishobora gukinwa muri Chrome n'izindi browser zigezweho, kandi mu settings ya High isaha imwe ni hafi MB 58. Imyitwarire yanjye: mba mbika WebM nk'archive hanyuma nkoresha MP3 gusa iyo umuntu abisabye.
Umukinnyi wemera gusa .ogg
OGG. Bamwe mubakinnyi b'ibitangazamakuru, moteri yimikino, nibikoresho bya Linux biteze Opus mubikoresho bya Ogg. Ubwiza bwamajwi buhuye WebM kumurongo umwe mwiza.

Imipaka inyangamugayo
-
Niba mushakisha yawe idashobora kuyitanga, popup ivuga "mushakisha yawe ntishobora gukora iyi format. Gerageza WAV cyangwa WebM."
- WebM na OGG ntibifunguka hose. Ibikoresho bimwe bya kera hamwe na bamwe mu bakinnyi b'imbere mu mikorere ya sisitemu babirengagiza. MP3 cyangwa WAV ni byo bifatika byo gusubizaho.
- Gusohora WAV na MP3 birebire bifata akanya, kuko igice cyose kibanza gusobanurwa. WAV y'isaha imwe isaba kandi ibyizamini byinshi bya megabytes biboneka mu bubiko bwawe bwa Downloads.
- Channels zikwirakwira kuri buri format. Ifoto ya Mono isohoka nka mono WAV cyangwa MP3; reba mono cyangwa stereo ku ijwi igihe Stereo ifite akamaro.
Niba wibuka urutonde rumwe rukenewe: fata amajwi mu Quality ushaka koko, ube ushyira WebM nka master, hanyuma usohore izindi format uko ubikeneye. Iyo ubanza gukata, gusohora kurimo igice cyonyine cyagumijwe — umurongo w'inyandiko ugaragaza intoki.
