MP4 chun AIFF Ceisteanna Coitianta maidir le Comhshó
Conas is féidir liom a bhaint as an fuaime ó MP4 comhad mar AIFF?
+
Uasluchtaigh an comhad MP4 agus déanfaimid an rian fuaime a dhí-mhúnlú, agus ansin é a thraschódú go AIFF. Níl aon dara pas físe agus níl aon chaillteanas cáilíochta ann thar an AIFF codec féin.
Cén giotánráta fuaime a úsáideann an comhad AIFF?
+
A lossy AIFF is encoded at 192 kbps by default. The Audio Quality setting also offers 320 kbps for the best quality and 128 kbps for a smaller file. A lossless AIFF (WAV, FLAC) ignores the bitrate and keeps every sample.
An gcaillfidh mé cáilíocht fuaime ag dul ó MP4 go AIFF?
+
Má tá an fhormáid AIFF gan chaillteanas (WAV, FLAC), coinníonn tú gach sampla go díreach. Má tá AIFF caillteanach (MP3, AAC, OGG), déanann an codec AIFF ath- chomhbhrú — braitheann an cháilíocht ar an ráta giotán agus ar an bhfoinse fuaime. Is é 192 kbps an réamhshocrú, atá trédhearcach do bheagnach gach ábhar.
An gcoinníonn an AIFF asbhainte an ráta samplála bunaidh?
+
De réir réamhshocraithe, tá — éiríonn rian fuaime 48 kHz i MP4 ina 48 kHz i AIFF. Má theastaíonn 44.1 kHz (cáilíocht CD) uait le haghaidh comhoiriúnachta le seinnteoirí níos sine, tá liosta anuas de ráta samplála sna hardroghanna.
An féidir liom a bhaint fuaime ó comhaid MP4 il go AIFF i mbaisc amháin?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Cé chomh fada a thógann sé AIFF a bhaint as comhad MP4?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
An féidir liom a bhaint ach cuid den MP4 fuaime mar AIFF?
+
Ní leis an uirlis seo — bain an fhuaim iomlán amach mar AIFF anseo, ansin bain úsáid as /audio-trim/ nó /audio-cutter/ chun an chuid a ghearradh. Is gnách go mbíonn an conair dhá chéim níos tapúla ná oibríocht chomhcheangailte.
An bhfuil mo chomhad MP4 príobháideach le linn eastóscadh fuaime?
+
Yes. Uploaded MP4 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted AIFF are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Cén fáth a bhfuil bearnaí ciúine i mo chomhad AIFF?
+
Usually the MP4 carries more than one audio track and the one that was converted is silent or secondary. The converter picks one audio track automatically, normally the main one, and this page has no setting to choose a different track. If the wrong one comes out, remux the MP4 with the track you want first (VLC or ffmpeg can do this) and convert it again.
An bhfuil an AIFF asbhainte ag imirt ar steirió iPhone / Android / carr?
+
MP3 plays almost everywhere. AAC plays on Apple devices, most Android phones and Sonos. OGG and Opus need a recent player on iOS but play in Chrome, Firefox and VLC. There are no device presets on this page, so choose the target format your player supports.
